Detailed Implementation

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] This invention proposes a rapid heating device 100, which guides the water flow through a guide member 30, stabilizing the water flow rate during heating, ensuring uniform heating, and reducing noise during operation. Additionally, a water dispenser is also proposed, which includes the aforementioned rapid heating device 100.

[0035] like Figures 1 to 5 According to an embodiment of the present invention, the rapid heating device 100 includes a housing 10, a heating tube 20, a flow guide 30, and an electrical connection assembly 40.

[0036] The outer casing 10 has an inlet 121 and an outlet 131. The outer casing 10 is equipped with a temperature monitoring device 90, which is used to monitor the temperature of the inlet 121 and / or the outlet 131. The heating tube 20 is disposed inside the outer casing 10. The heating tube 20 has an inner cavity that connects the inlet 121 and the outlet 131. The heating tube 20 is configured to heat the fluid in the inner cavity. The flow guide 30 is disposed in the inner cavity, and there is a fluid channel between the flow guide 30 and the heating tube 20. The electrical connection assembly 40 is electrically connected to the heating tube 20, and the electrical connection assembly 40 is connected to one end of the heating tube 20.

[0037] Specifically, when the rapid heating device 100 is working, the water flow can flow through the inlet, the inner cavity and the outlet 131 in sequence. A guide 30 is provided in the inner cavity, and a fluid channel is formed between the guide 30 and the heating tube 20. The water flow can flow through the fluid channel. Through the guiding effect of the guide 30, the water flow can flow stably through the rapid heating device 100, reducing the noise generated by the water flow in the rapid heating device 100, and making it easier for the heating tube 20 to heat the water flow evenly, so as to achieve the purpose of precise temperature control.

[0038] In addition, the electrical connection component 40 is located at one end of the heating tube 20, which facilitates the assembly of the rapid heating device 100 inside the water dispenser. It can be understood that when installing the rapid heating device 100, it can be connected to the water system inside the water dispenser through the water inlet 121 and water outlet 131 of the outer casing 10. The electrical connection component 40 is located at one end of the heating tube 20, that is, the electrical connection component 40 is located near the water inlet 121 of the outer casing 10. During assembly, it is convenient to connect the electrical connection component 40 to the wiring harness to realize the heating function of the heating tube 20.

[0039] Furthermore, it is understandable that the heating element 20 and the flow guide 30 are housed inside the housing 10, which provides protection and prevents the external environment from affecting the normal operation of the heating element 20, the flow guide 30, etc.

[0040] Furthermore, the outer casing 10 is equipped with a temperature monitoring element 90. It is understood that the temperature monitoring element 90 can monitor the temperature of the inlet 121 and / or the outlet 131 to ensure that the inlet and outlet water temperatures of the rapid heating device 100 meet the preset range, thereby achieving more precise temperature control.

[0041] Therefore, according to the embodiment of the present invention, the rapid heating device 100 guides the water flow through the guide member 30, which can stabilize the water flow rate during heating, so that the water flow is heated evenly and the noise generated during operation is reduced.

[0042] like Figures 1 to 4 In some embodiments of this utility model, the outer casing 10 includes a water inlet connector 12 and a water outlet connector 13, which are respectively connected to the two ends of the heating tube 20. At least one of the water inlet connector 12 and the water outlet connector 13 is provided with a temperature monitoring element 90. It can be understood that the rapid heating device 100 can be applied in a water dispenser. The rapid heating device 100 can be quickly connected to the water system in the water dispenser through the water inlet connector 12 and the water outlet connector 13, thereby improving assembly efficiency. In some specific examples, the water inlet connector 12 is provided with an inlet water temperature monitoring element 91, which can monitor the water flow temperature at the water inlet 121, and the water outlet connector 13 is provided with an outlet water temperature monitoring element 92, which can monitor the water flow temperature at the water outlet 131. In this way, precise temperature control of water flow heating can be achieved.

[0043] In addition, the water inlet connector 12 has the aforementioned water inlet 121, and the water outlet connector 13 has the aforementioned water outlet 131.

[0044] like Figures 1 to 4 In some embodiments of this utility model, the rapid heating device 100 further includes a temperature control switch 50 and a temperature limiter 60. The temperature control switch 50 and the temperature limiter 60 are disposed on the outer casing 10 and are in contact with the heating tube 20. In this way, the safe operation of the rapid heating device 100 can be ensured and damage caused by excessive temperature can be avoided.

[0045] For example, the rapid heating device 100 is arranged vertically, with the water inlet 121 of the rapid heating device 100 at the bottom and the water outlet 131 of the rapid heating device 100 at the top. The temperature control switch 50 is located above the temperature limiter 60. When the heating tube 20 overheats, the heat near the temperature control switch 50 is greater than the heat near the temperature limiter, so the temperature control switch 50 is triggered first to control the rapid heating device 100 to stop operating. If the temperature control switch 50 fails, the temperature limiter 60 is triggered to control the rapid heating device 100 to stop operating. The temperature limiter 60 is a redundant design and, together with the temperature control switch 50, achieves a double insurance effect, which can further improve the safety of the rapid heating device 100. In addition, the temperature control switch 50 can automatically reset. For example, if the temperature of the rapid heating device 100 drops after the temperature control switch 50 is triggered, the temperature control switch 50 can reset to the state before the trigger. The temperature limiter 60 needs to be manually reset. For example, if the temperature of the rapid heating device 100 drops after the temperature limiter 60 is triggered, the temperature limiter 60 cannot reset to the state before the trigger. The user needs to remove the rapid heating device 100 and manually reset the temperature limiter 60 to the state before the trigger. This can further improve the safety of the rapid heating device 100 and avoid the risk of the temperature limiter 60 malfunctioning.

[0046] like Figures 1 to 4 In some embodiments of this utility model, the outer shell 10 further includes a protective shell 11, which is disposed outside the heating tube 20. The temperature control switch 50 and the temperature limiter 60 are disposed on the protective shell 11 and contact the peripheral wall of the heating tube 20. Specifically, the heating tube 20 is disposed inside the protective shell 11, and the two ends of the protective shell 11 are respectively connected to the water inlet connector 12 and the water outlet connector 13. The protective shell 11 can isolate the heating tube 20 from the external environment, preventing the heating tube 20 from damaging other structural components inside the water dispenser, and also preventing the external environment from affecting the normal operation of the heating tube 20.

[0047] In addition, the protective shell 11 has a first mounting hole and a second mounting hole. The temperature control switch 50 passes through the first mounting hole to contact the peripheral wall of the heating tube 20 and is connected to the periphery of the first mounting hole by fasteners. The temperature limiter 60 passes through the second mounting hole to contact the peripheral wall of the heating tube 20 and is connected to the periphery of the second mounting hole by fasteners. In this way, it is convenient to disassemble and replace the temperature control switch 50 and the limiter, and improve the ease of disassembly and assembly.

[0048] like Figures 1 to 4 In some embodiments of this utility model, in conjunction with the foregoing, the water inlet 121 is provided at the water inlet connector 12, and the water inlet 121 is configured such that its axis extends along the axis of the heating tube 20. In this way, the structure of the water inlet connector 12 is simple and easy to manufacture, and when the rapid heating device 100 is arranged vertically, the space occupied by the rapid heating device 100 in the water dispenser can be reduced, making the structure of the water dispenser thinner. Similarly, the water outlet 131 is provided at the water outlet connector 13, and the water outlet 131 is configured such that its axis extends along the axis of the heating tube 20. In this way, the structure of the water outlet connector 13 is simple and easy to manufacture, and when the rapid heating device 100 is arranged vertically, the space occupied by the rapid heating device 100 in the water dispenser can be reduced.

[0049] like Figures 2 to 4 In some embodiments of this utility model, the heating tube 20 includes a first tube body 21 and a heating part 22. The inner cavity is disposed inside the first tube body 21, and the heating part 22 is laid on the peripheral wall of the first tube body 21. In this way, the heating part 22 can uniformly heat the peripheral wall of the first tube body 21, which facilitates the first tube body 21 to uniformly transfer heat to the water flow and improve the heating uniformity of the water flow.

[0050] In some examples, the heating element 22 is laid on the outer peripheral wall of the first tube body 21, and the first tube body 21 is provided with a flow guide 30. A fluid channel is formed between the flow guide 30 and the inner peripheral wall of the first tube body 21. The water flows along the fluid channel and receives the heat emitted by the heating element 22, thereby achieving uniform heating of the water flow. This also reduces the space occupied by the heating element 22 in the inner cavity and facilitates the assembly of the flow guide 30.

[0051] like Figure 2 and Figure 3 In some embodiments of this utility model, the heating part 22 includes a plurality of heating branches 221, which are distributed circumferentially along the first tube body 21 and extend axially along the first tube body 21. The plurality of heating branches 221 are connected end to end in a meandering manner. In this way, the heating part 22 can uniformly cover the circumferential wall of the first tube body 21, improve the heating uniformity of the water flow by the heating tube 20, and achieve precise temperature control of the water flow.

[0052] For example, the heating part 22 includes a first heating branch 221 and a second heating branch 221. Both the first heating branch 221 and the second heating branch 221 extend along the axis of the first tube part 21 and have opposite ends. One end of the first heating branch 221 is a free end, and the other end of the first heating branch 221 is connected to the other end of the second heating branch 221. One end of the second heating branch 221 is a free end. In this way, the first heating branch 221 and the second heating branch 221 can be connected end to end in a meandering manner so that the heating part 22 is evenly arranged on the peripheral wall of the first tube part 21, thereby uniformly heating the water flowing through the first tube part 21.

[0053] like Figure 2 and Figure 3 In some embodiments of this utility model, the first end of the heating part 22 is configured as a first terminal 222, and the tail end of the heating part 22 is configured as a second terminal 223. The first terminal 222 and the second terminal 223 are located at the same end of the first tube body 21. In this way, it is convenient to connect the heating part 22 to the electrical connection assembly 40 and improve the assembly efficiency.

[0054] In conjunction with the foregoing, one end of the first heating support 221 is set as the beginning end of the heating section 22 and configured as the first terminal 222, and one end of the second heating support 221 is set as the end end of the heating section 22 and configured as the second terminal 223. The heating section 222 is formed by connecting the beginning and end of the first heating support 221 and the second heating support 221, and the beginning and end of the heating section 22 are set in the same section of the first tube body 21, which facilitates the electrical connection of the heating section 22 to the electrical connection assembly 40 and improves the assembly efficiency of the rapid heating device 100.

[0055] like Figure 2 and Figure 3 In some embodiments of this utility model, the heating tube 20 further includes an insulating part 23, which is laid on the peripheral wall of the first tube body 21 and separates adjacent heating branches 221; in this way, electrical leakage between heating branches 221 is avoided, and the safety of the rapid heating device 100 is improved.

[0056] For example, the first heating branch 221 and the second heating branch 221 are arranged adjacent to each other and spaced apart to avoid the first heating branch 221 and the second heating branch 221 being too close to cause local heat concentration, and to allow the first heating branch 221 and the second heating branch 221 to be spaced apart by a predetermined safe distance. Furthermore, an insulating part 23 may be provided in the gap between the first heating branch 221 and the second heating branch 221 to prevent leakage of electricity when the first heating branch 221 and the second heating branch 221 are energized for heating, thereby affecting the normal operation of the rapid heating device 100 and improving the safety of the rapid heating device 100.

[0057] like Figure 2 and Figure 3 In some embodiments of this utility model, the insulating part 23 includes a plurality of insulating supports 231, which are distributed circumferentially along the first tube part 21 and extend axially or radially along the first tube part 21. An insulating support 231 is provided between each pair of adjacent heating supports 221. In this way, the insulating part 23 can uniformly cover the peripheral wall of the first tube part 21, thereby improving the safety of the rapid heating device 100.

[0058] It is understandable that, taking the extension of the insulating branch 231 along the axial direction of the first tube body 21 as an example: two adjacent heating branches 221 among the multiple heating branches 221 are spaced apart to avoid local heat concentration, which would affect the normal operation of the multiple heating branches 221, and to allow the multiple heating branches 221 to be spaced apart by a predetermined safe distance, thus avoiding safety hazards caused by conductive contact; in addition, an insulating branch 231 is provided between each pair of adjacent heating branches 221, which separates the two adjacent heating branches 221 and prevents leakage when the heating branches 221 are conducting electricity; furthermore, both the insulating branch 231 and the heating branch 221 extend along the axial direction of the first tube body 21, which facilitates the insulating branch 231 to separate adjacent heating branches 221 and improve the insulation effect.

[0059] Furthermore, taking the radial extension of the insulating support 231 along the first tube body 21 as an example: the insulating part 23 includes multiple insulating supports 231, which are distributed circumferentially along the first tube body 21 and extend radially along the first tube body 21. An insulating support 231 is provided between each pair of adjacent heating supports 221. This allows the insulating supports 231 to have a certain thickness, enabling the first tube body 21 and the heating part 22 to be separated from the protective shell 11 or external structure by a predetermined distance, improving the safety of the rapid heating device 100 and preventing leakage hazards. The insulating supports 231 also separate adjacent heating supports 221 by a predetermined safe distance, preventing safety hazards.

[0060] like Figure 2 and Figure 3 In some embodiments of this utility model, the heating part 22 has a first terminal 222, a second terminal 223, and a grounding terminal 224. The first terminal 222, the second terminal 223, and the grounding terminal 224 are located at the same end of the heating tube 20. The electrical connection assembly 40 includes a first terminal 41, a second terminal 42, and a third terminal 43. The first terminal 41 is connected to the first terminal 222, the second terminal 42 is connected to the second terminal 223, and the third terminal 43 is connected to the grounding terminal 224. In this way, it is convenient to assemble the electrical connection assembly 40 with the heating tube 20 and improve the assembly efficiency.

[0061] For example, the first terminal 222 of the heating unit 22 is provided with a positive terminal, the second terminal 223 of the heating unit 22 is provided with a negative terminal, the first terminal 41 of the electrical connection assembly 40 is provided with a positive terminal, the second terminal 42 of the electrical connection assembly 40 is provided with a negative terminal, the positive terminal of the heating unit 22 is electrically connected to the external wiring harness through the positive terminal, the negative terminal of the heating unit 22 is electrically connected to the external wiring harness through the negative terminal, and the ground terminal 224 of the heating unit 22 is connected to the external wiring harness through the third terminal 43. In this way, the heating unit 22 can be connected to the power supply to heat the water flow, and the stability of the electrical connection can be improved by the electrical connection assembly 40, thereby improving the operational stability of the rapid heating device 100.

[0062] Furthermore, the first terminal 222, the second terminal 223, and the grounding terminal 224 of the heating unit 22 are all located at the same end of the heating tube 20, which facilitates the assembly and connection between the heating unit 22 and the electrical connection assembly 40 and improves assembly efficiency. In addition, the connection between the grounding terminal 224 and the third terminal 43 can ground the heating unit 22 to prevent damage to the rapid heating device 100 in the event of leakage from the heating unit 22.

[0063] like Figures 2 to 4 In some embodiments of this utility model, the heating part 22 is configured as a diaphragm heating structure. In this way, the heating part 22 can be evenly laid on the peripheral wall of the first tube part 21 through the diaphragm heating structure, so that the heating part 22 can evenly heat the water flow in the first tube part 21, making the water dispenser hotter and improving the user experience.

[0064] like Figures 1 to 4 In some other embodiments of the present invention, the rapid heating device 100 further includes a grounding part 24, which is connected to the first tube body 21. This configuration allows the first tube body 21 to be grounded through the grounding part 24, preventing damage to the first tube body 21 when the rapid heating device 100 leaks electricity.

[0065] like Figures 1 to 3 In some embodiments of this utility model, the end of the outer shell 10 is provided with a clearance notch 14, the electrical connection component 40 passes through the clearance notch 14 and is electrically connected to the heating tube 20; in this way, the space occupied by the quick heating device 100 can be reduced and the space utilization rate of the water dispenser can be improved.

[0066] For example, the end of the housing 10 is provided with a clearance notch 14, and the outer surface of the end of the housing 10 is provided with a first fixing seat, a second fixing seat, and a third fixing seat. The first wiring portion 41 can pass through the clearance notch 14. One end of the first wiring portion 41 can be connected to the first wiring terminal 222 of the heating part 22, and the other end can be fixed on the first fixing seat. An external wiring harness can be connected to the first fixing seat to be electrically connected to the first wiring terminal 222. The second wiring portion 42 can pass through the clearance notch 14. One end of the second wiring portion 42 can be connected to the second wiring terminal 223 of the heating part 22, and the other end can be fixed on the first fixing seat. On the second fixed base, the external wiring harness can be connected to the second fixed base to be electrically connected to the second wiring part 42; the third wiring part 43 can be passed through the clearance notch 14, one end of the third wiring part 43 can be connected to the ground terminal 224 of the heating part 22, and the other end can be fixed on the ground fixed base. The external wiring harness can be connected to the third fixed base to be electrically connected to the third wiring part 43. In short, the electrical connection component 40 can be passed through the clearance notch 14 so that the structure of the electrical connection component 40 is more concentrated on the rapid heating device 100, improving the integration, reducing the volume of the rapid heating device 100, and reducing the space occupation.

[0067] like Figure 4 and Figure 5 In some embodiments of this utility model, the rapid heating device 100 further includes an inlet water diversion section 70 and an outlet water confluence section 80, which are respectively located at opposite ends of the heating tube 20. Specifically, when the water flows through the heating tube 20, the water flow can first be diverted by the inlet water diversion section 70, so that the water flow can be evenly distributed into the fluid channel, and under the guiding action of the guide member 30, it flows to the outlet water confluence section 80. The water flow is then subjected to the backflow action of the outlet water confluence section 80 and is concentrated and discharged from the outlet 131. During this process, it is convenient for the heating tube 20 to heat the water flow evenly and improve the heat uniformity of the water flow.

[0068] More specifically, at least one of the inlet water diversion section 70 and the outlet water confluence section 80 includes: a flow equalization section, which covers the end of the fluid channel and is provided with a plurality of flow equalization holes, which are distributed circumferentially along the heating tube 20; thus, the plurality of flow equalization holes can realize the diversion and confluence of water flow, which facilitates the heating tube 20 to heat the water flow evenly.

[0069] As described above, in some examples, the inlet water distribution section 70 includes a first flow equalization section 71, which includes a plurality of first flow equalization holes 711, and the outlet water confluence section 80 includes a second flow equalization section 81, which includes a plurality of second flow equalization holes 811. When the water flows through the heating pipe 20, the water can flow through the plurality of first flow equalization holes 711, which distribute the water flow into the fluid channel, so that the water flows evenly in the fluid channel. Subsequently, the water can flow through the plurality of second flow equalization holes 811, which concentrate the water flow and discharge it from the outlet 131.

[0070] like Figure 4 and Figure 5 In some embodiments of this utility model, the flow guide 30 includes a second tube body 31 and a flow guide 32. The second tube body 31 is disposed inside the heating tube 20 and extends in the same direction as the heating tube 20. The flow guide 32 is disposed on the outer peripheral surface of the second tube body 31 and is located between the second tube body 31 and the heating tube 20. The flow guide 32 is designed to extend spirally along the axial direction of the second tube body 31. In this way, the flow guide 30 can guide the water flow to flow evenly in the heating tube 20, which facilitates the heating tube 20 to heat the water flow evenly and achieve precise temperature control.

[0071] It is understandable that the guide section 32 extends spirally along the axial direction of the second tube body 31 to form a spiral guide section 32. When the water flows through the fluid channel, it can flow spirally along the guide section 32, so that the water flows evenly in the fluid channel and can prolong the flow time of the water in the fluid channel. This makes it easier for the heating tube 20 to heat the water evenly and achieve precise temperature control of the water.

[0072] Preferably, the guide section 32 is plate-shaped, that is, it extends spirally along the second tube body 31 to increase the guide area of ​​the guide section 32, so that the water flows evenly along the fluid channel, which facilitates the heating tube 20 to heat the water evenly.

[0073] In addition, at least one of the inlet water diversion section 70 and the outlet water confluence section 80 also includes a plug, which seals the end of the second pipe body section 31. The plug is connected to the inner periphery of the flow equalization section, and a plurality of flow equalization holes are provided on the outer periphery of the flow equalization section. In this way, the inlet water diversion section 70 and the outlet water confluence section 80 can be installed on the second pipe body section 31, and water flow is prevented from entering the second pipe body section 31.

[0074] As described above, in some examples, the inlet water diversion section 70 further includes a first plug 72, which blocks one end of the second pipe body section 31 so that the inlet water diversion section 70 is installed on the second pipe body. The inlet water diversion section 70 can block one end of the second pipe body section 31 to prevent water from entering the second pipe body section 31 and affecting the uniform flow and heating of the water. Similarly, the outlet water confluence section 80 also includes a second plug 82, which blocks the other end of the second pipe body section 31 so that the outlet water confluence section 80 is installed on the second pipe body. The outlet water confluence section 80 can block the other end of the second pipe body section 31 to prevent water from entering the second pipe body section 31 and affecting the uniform flow and heating of the water.

[0075] like Figures 1 to 5 According to the embodiments of the present utility model, the water dispenser includes the rapid heating device 100 in the above embodiments. By applying the aforementioned rapid heating device 100, precise temperature control of the water flow can be achieved, and the noise of the water dispenser can be reduced.

[0076] Specifically, the rapid heating device 100 can be used in water dispensers. Since the rapid heating device 100 in this embodiment has good temperature control, it can be used in water dispensers without a water tank. It is understood that the rapid heating device 100 can make the water flow evenly through it and heat the water evenly, with a precise temperature control effect. Therefore, there is no need to set up a water tank in the water dispenser for buffering. In this way, the size of the water dispenser is reduced and the integration of the water dispenser is improved.

[0077] Working principle of the rapid heating device 100:

[0078] Water flows into the rapid heating device 100 through the inlet 121. Under the diversion action of the inlet diversion section 70, the water flow is divided into multiple parts. Under the guidance action of the guide section 32, the water flows evenly in the fluid channel. Under the diversion action of the outlet confluence section 80, the water flow converges and is discharged from the rapid heating device 100 through the outlet 131 to reduce the noise generated by the water flow impact. During this process, the heating section 22 is laid on the first pipe section 21 to heat the water flow in the fluid channel evenly. This can improve the uniformity of water heating and achieve precise temperature control of the water flow.

[0079] Furthermore, multiple heating branches 221 are spaced apart and distributed around the circumference of the first tube body 21, extending along the axis of the first tube body 21 and extending in a meandering manner to cover the circumferential wall of the first tube body 21, thereby improving the uniformity of water heating. An insulating branch 231 is provided between adjacent heating branches 221 to separate them and prevent electrical leakage hazards between adjacent heating branches 221.

[0080] Furthermore, the first terminal 222, the second terminal 223, and the grounding terminal 224 of the heating part 22 are located at the same end of the heating tube 20, and the first terminal 41, the second terminal 42, and the third terminal 43 of the electrical connection assembly 40 are also located at the same end of the housing 10, which facilitates the connection between the electrical connection assembly 40 and the heating tube 20 and improves assembly efficiency.

[0081] In some specific examples, with the instant heating component (i.e., the rapid heating device 100) installed vertically, water flows into the instant heating pipe (i.e., the heating pipe 20) through the inlet cap (i.e., the inlet connector 12). Under the guidance of the metal flow guide column assembly (i.e., the flow guide component 30), the water flows through the side hole of the flow-limiting sealing ring (i.e., the flow equalization hole) into the interior of the instant heating pipe, and rises evenly in a spiral along the metal flow guide assembly, thereby making the water heated evenly and the water flow gentle, reducing the bubbles generated by water flow cross-temperature during the heating process, and reducing heating noise and water flow fluctuations. Considering the installation of the flow guide column assembly and the implementation of the flow guiding function, there is a gap of 0.1mm-0.5mm between the outer diameter of the flow guide column assembly and the inner diameter of the instant heating pipe. This gap can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc. Note: For water quality hygiene, the material of this flow guide column assembly is 304 stainless steel.
