[0038] An instant hot water bottle (or kettle) is a heating tool that uses a heater to quickly heat a portion of water, allowing users to obtain hot water quickly.

[0039] Existing instant hot water kettles use a semiconductor cooling element installed in the heated, warm water storage tank. When an iced drink is desired, a freeze switch is pressed, activating the semiconductor cooling element to directly cool the warm water. Once the desired temperature is reached, the ice-cold water valve is opened to obtain chilled water. While this achieves rapid cooling, the separate cooling device consumes a significant amount of energy, resulting in high energy consumption and being detrimental to energy conservation and environmental protection.

[0040] The following is combined with Figure 1 and Figure 2 The liquid heating device provided in this utility model will be described in detail through specific embodiments and application scenarios.

[0041] In the embodiments of the utility model, reference is made to... Figure 1 and Figure 2The liquid heating device 10 includes a water tank assembly 100, a liquid heating assembly 200, and a heat exchange assembly 300. The water tank assembly 100 has a first liquid storage chamber 111, which is suitable for storing liquid media. The water tank assembly 100 includes a circulating water passage 130, both ends of which are connected to the first liquid storage chamber 111. The liquid heating assembly 200 has a second liquid storage chamber 211 and a heating device, which is suitable for heating the liquid media in the second liquid storage chamber. The liquid heating assembly 200 includes a drinking water passage 230, which is connected to the second liquid storage chamber 211. The heat exchange assembly 300 is coupled between the circulating water passage 130 and the drinking water passage 230. The heat exchange assembly 300 cools the liquid media in the drinking water passage 230 by exchanging heat between the liquid media in the circulating water passage 130 and the liquid media in the drinking water passage 230.

[0042] In this embodiment, the water tank assembly 100 serves as the liquid storage center of the entire device, and the first liquid storage chamber 111 is responsible for storing the liquid medium (such as drinking water) to be heated and supplied. This ensures that the device can meet the user's continuous needs with a certain amount of liquid medium and provides the basis for liquid heating and heat exchange.

[0043] The circulating water passage 130 connects the two ends of the first liquid storage chamber 111, allowing the water in the first liquid storage chamber 111 to form a circulating flow path. When hot water is cooled by the heat exchange component 300, the cold water in the first liquid storage chamber 111 travels through the circulating water passage 130 to the heat exchange component 300 to exchange heat with the hot water in the drinking water passage 230, absorbs heat, and then returns to the first liquid storage chamber 111. The circulating water passage 130 ensures that the water in the first liquid storage chamber 111 can continuously participate in the heat exchange process, maintaining a stable water temperature, and also facilitates the user to replenish the water in the first liquid storage chamber 111 into the liquid heating component 200 for heating.

[0044] The inlet of the circulating water passage 130 is connected to the bottom of the first liquid storage chamber 111, while the outlet of the circulating water passage 130, i.e. the return water port 131, is connected to the top of the first liquid storage chamber 111. The hot water and cold water in the first liquid storage chamber 111 will achieve the effect of hot at the top and cold at the bottom due to the temperature difference, and the lower temperature liquid medium will be continuously input into the circulating water passage 130 for cooling.

[0045] The second liquid storage chamber 211 in the liquid heating assembly 200 is a space for heating the liquid medium. The user adds water that needs to be heated into the second liquid storage chamber 211, and the water is heated to boiling by the heating element 221.

[0046] The drinking water passage 230 connects the second liquid storage chamber 211 and the water outlet, delivering heated water to the user. Simultaneously, the drinking water passage 230 also serves as a crucial channel for heat exchange in the heat exchange component 300, allowing the hot water to release some heat to the liquid medium in the circulating water passage 130 before flowing out, thereby cooling the liquid medium in the drinking water passage 230.

[0047] The drinking water passage 230 ensures that the heated water can be smoothly guided to the cooling stage, while also providing a channel for hot water output.

[0048] The heat exchange component 300 is coupled between the circulating water passage 130 and the drinking water passage 230. Its purpose is to use the cold water in the first liquid storage chamber 111 as a cooling medium and, through the principle of heat exchange, to quickly cool the hot water in the drinking water passage 230 to a suitable drinking temperature.

[0049] It should be noted that, in this application, the coupling connection refers to connecting the heat exchange module to the water pipes (circulating water passage 130 and drinking water passage 230) via mechanical connectors, so that fluids can flow between them and exchange heat. The coupling connection ensures good thermal contact between the heat transfer surface of the heat exchange module and the water pipe, so that heat can be transferred from one medium to another.

[0050] Among them, the heat exchange component 300 adopts materials such as metal pipes and metal plates to realize the heat transfer between hot water in the drinking water passage 230 and cold water in the circulating water passage 130.

[0051] This application incorporates a heat exchange component 300 coupled to the circulating water passage 130 and the drinking water passage 230. The heat exchange component 300 enables heat exchange between these two passages. Specifically, when hot water in the liquid heating component 200 passes through the heat exchange component 300, it releases heat and its temperature decreases; conversely, when water in the first liquid storage chamber 111 passes through the heat exchange component 300, it absorbs heat from the drinking water passage 230 and its temperature increases. Therefore, the water temperature in the first liquid storage chamber 111 rises, while the hot water output from the drinking water passage 230 remains relatively constant. This allows for rapid heating of water to boiling and then rapid cooling to a suitable temperature. Furthermore, since the heat exchange component 300 primarily exchanges heat between the water in the first liquid storage chamber 111 and the drinking water passage 230, it does not require excessive additional energy for cooling, effectively improving energy recycling efficiency and achieving energy savings.

[0052] Reference Figure 1According to one embodiment of the present invention, the drinking water passage 230 includes a first water outlet section 231 and a second water outlet section 232. The end of the first water outlet section 231 is provided with a first water outlet 231a, and the end of the second water outlet section 232 is provided with a second water outlet 232a. The heat exchange component 300 is coupled to the second water outlet section 232.

[0053] It is understandable that dividing the drinking water passage 230 into a first outlet section 231 and a second outlet section 232 allows the water to undergo different treatment stages during the outflow process, thereby improving the flexibility and controllability of the device.

[0054] Specifically, the first outlet 231a is located at the end of the first outlet section 231 and can be used directly to supply hot water without heat exchange treatment, or as a backup outlet. This provides users with more options, allowing them to choose higher temperature hot water as needed.

[0055] The second water outlet 232a is located at the end of the second water outlet section 232. Since the second water outlet section 232 is coupled to the heat exchange component 300, the water supplied by this outlet is water that has undergone heat exchange treatment and is at a more suitable temperature, in order to meet the daily drinking water needs of most users.

[0056] In this embodiment, the heat exchange component 300 is coupled to the second water outlet section 232. Hot water undergoes cooling treatment via the heat exchange component 300 before flowing out to the second water outlet 232a. This ensures that the water flowing out of the second water outlet 232a remains within a suitable temperature range, improving user comfort. By cooling the hot water in the second water outlet section 232 through the heat exchange component 300, the water in the circulating water passage 130 is simultaneously heated, achieving effective heat recovery and utilization. This design reduces energy waste and improves the system's energy efficiency.

[0057] Of course, in other embodiments, the drinking water passage 230 may be provided with only one outlet or two or more outlets. No special limitation is made here, and the arrangement can be made according to specific needs.

[0058] Reference Figure 1 According to one embodiment of the present invention, a second solenoid valve assembly 240 is provided between the first water outlet section 231 and the second water outlet section 232. The second solenoid valve assembly 240 is suitable for controlling the on / off state of the first water outlet section 231 and the second water outlet section 232.

[0059] Understandably, the second solenoid valve assembly 240 is installed at the junction between the first outlet section 231 and the second outlet section 232 to control the direction of water flow. When the solenoid valve opens or closes, it determines whether hot water flows out from the first outlet section 231 or the second outlet section 232. Thus, through the control of the solenoid valve, the user can select the hot water temperature according to actual needs, thereby improving the flexibility and convenience of the device.

[0060] Specifically, when high-temperature hot water is needed, the second solenoid valve assembly 240 closes the second outlet section 232, allowing hot water to flow only through the first outlet section 231 from the first outlet 231a. When warm water is needed, the second solenoid valve assembly 240 closes the first outlet section 231, allowing the hot water to enter the heat exchange assembly 300 through the second outlet section 232 for cooling before flowing out from the second outlet 232a.

[0061] Reference Figure 1 According to one embodiment of the present invention, a first pump assembly 250 is provided on the drinking water passage 230, and the first pump assembly 250 is suitable for adjusting the water flow rate of the drinking water passage 230.

[0062] It is understood that in this embodiment, by providing a first pump assembly 250 on the drinking water passage 230, the speed at which hot water passes through the heat exchange assembly 300 can be controlled by adjusting the operating state of the pump assembly, thereby affecting the cooling effect of the hot water. Thus, by adjusting the first pump assembly 250, precise control of the hot water temperature can be achieved, ensuring that users can obtain hot water at the desired temperature. Simultaneously, the first pump assembly 250 can also be used to control the on / off state of the drinking water passage 230.

[0063] Specifically, when a user needs hot water at high temperatures, the first pump water assembly 250 can be adjusted to a higher flow rate, allowing hot water to quickly pass through the heat exchange assembly 300, reducing the contact time with cold water and thus maintaining a higher water temperature. When a user needs warm water, the first pump water assembly 250 can be adjusted to a lower flow rate, allowing the hot water to stay in the heat exchange assembly 300 for a longer time, increasing the heat exchange area with cold water, thereby achieving a better cooling effect.

[0064] Reference Figure 1 A second pump assembly 160 is provided on the circulating water passage 130. The second pump assembly 160 is suitable for adjusting the water flow rate of the circulating water passage 130.

[0065] Understandably, the second pump assembly 160 is installed on the circulating water passage 130 to regulate the water flow rate through the passage. By adjusting the operating state of the pump assembly, the speed at which cold water in the first storage chamber 111 passes through the heat exchange component 300 can be controlled, thereby affecting the hot water cooling effect. This achieves precise control of the hot water temperature, ensuring that users can obtain hot water at the desired temperature. Simultaneously, the second pump assembly 160 can also be used to control the on / off state of the circulating water passage 130.

[0066] Specifically, when a user requires high-temperature hot water, the second pump assembly 160 can be adjusted to a lower flow rate, slowing down the flow of cold water in the first storage chamber 111 through the heat exchange assembly 300, reducing the contact time with the hot water, and thus maintaining a higher water temperature. When a user requires warm water, the second pump assembly 160 can be adjusted to a higher flow rate, accelerating the flow of cold water in the first storage chamber 111 through the heat exchange assembly 300, increasing the contact time with the hot water, and thus achieving a better cooling effect.

[0067] The first pump assembly 250 regulates the flow rate of hot water in the drinking water passage 230, while the second pump assembly 160 regulates the flow rate of cold water in the circulating water passage 130. The two work together to determine the rate at which the hot water cools down and its final temperature.

[0068] Reference Figure 1 According to one embodiment of the present invention, the liquid heating assembly 200 further includes a first temperature measuring assembly 260, which is suitable for detecting the temperature of the liquid medium in the second liquid storage chamber 211.

[0069] Understandably, the first temperature sensing component 260 is installed inside the second liquid storage chamber 211 to monitor the temperature of the liquid medium within the chamber in real time. During the heating phase, the first temperature sensing component 260 monitors the water temperature in the second liquid storage chamber 211 in real time and feeds the data back to the control system. When the detected water temperature reaches a preset value, the control system sends a command to stop heating. During the cooling phase, based on the user's selected desired hot water mode, the heated hot water enters the heat exchange component 300 through the second outlet section 232 for cooling. The first temperature sensing component 260 continues to monitor the temperature of the remaining hot water in the second liquid storage chamber 211. The control system adjusts the operating status of the first water pump component 250 and the second water pump component 160 based on the temperature data to ensure that the hot water achieves the expected cooling effect when passing through the heat exchange component 300. Users can accurately obtain hot water at the desired temperature, improving the product's user experience.

[0070] Reference Figure 1 The water tank assembly 100 also includes a second temperature measuring assembly 170, which is suitable for detecting the temperature of the liquid medium in the first liquid storage chamber 111.

[0071] Understandably, the second temperature sensing component 170 is installed inside the first liquid storage chamber 111 of the water tank assembly 100 to monitor the temperature of the liquid medium (usually cold water) inside the first liquid storage chamber 111 in real time. Using the data acquired by the second temperature sensing component 170, the control system can precisely control the heat exchange process, ensuring that the hot water can be quickly cooled to a suitable drinking temperature. The temperature data provided by the second temperature sensing component 170 is the foundation for achieving precise temperature control, ensuring that users can obtain hot water at the required temperature and effectively utilize the cold water inside the first liquid storage chamber 111 for heat exchange.

[0072] Specifically, based on the user's selected hot / warm water mode, the heated water will enter the heat exchange component 300 for cooling through the second outlet section 232. The second temperature sensing component 170 monitors the temperature of the cold water in the first liquid storage chamber 111 in real time and feeds the data back to the control system. The control system adjusts the operating states of the first pumping component 250 and the second pumping component 160 based on the temperature of the hot water in the second liquid storage chamber 211 (provided by the first temperature sensing component 260) and the temperature of the cold water in the first liquid storage chamber 111 (provided by the second temperature sensing component 170) to ensure that the hot water achieves the expected cooling effect when passing through the heat exchange component 300. By monitoring the temperature of the cold water in the first liquid storage chamber 111 in real time, the control system can optimize the use of cold water and reduce unnecessary energy consumption.

[0073] Reference Figure 1 According to one embodiment of the present invention, the water tank assembly 100 includes a water tank 110 and a base 120. A first liquid storage chamber 111 is located inside the water tank 110. The water tank 110 is detachably connected to the base 120. One end of the circulating water passage 130 is connected to the water tank 110 through the base 120.

[0074] Understandably, the detachable connection between the water tank 110 and the base 120 makes the entire water tank assembly 100 more modular, facilitating maintenance and cleaning. When it is necessary to clean the inside of the water tank 110 or inspect the connecting parts of the base 120, the user can easily remove the water tank 110 from the base 120, complete the necessary work, and then reinstall it. This improves the ease of use and cleanliness of the device.

[0075] Of course, in other embodiments, the water tank assembly 100 may also include a lid and a handle, etc.

[0076] Reference Figure 1According to one embodiment of the present invention, the liquid heating assembly 200 includes a liquid heating container 210 and a base 220. A second liquid storage chamber 211 is located inside the liquid heating container 210. The second liquid storage chamber 211 is at least partially transparent and visible to the outer wall surface of the liquid heating container 210. The liquid heating container 210 is detachably connected to the base 220. The drinking water passage 230 is connected to the liquid heating container 210 through the base 220.

[0077] It is understood that the liquid heating container 210 is used to store the liquid medium to be heated (such as drinking water), and the second liquid storage chamber 211 is located inside the liquid heating container 210 and is used to heat the liquid medium.

[0078] The base 220 serves as a support structure for the liquid heating container 210 and also as a bridge connecting the heating element and the water tank assembly 100. Through the base 220, the drinking water passage 230 is connected to the second liquid storage chamber 211 inside the liquid heating container 210. The base 220 not only provides stable support but also ensures the correct connection between the heating element and the water tank assembly 100.

[0079] The liquid heating container 210 is detachably connected to the base 220, allowing users to easily remove the liquid heating container 210 from the base 220 for adding, emptying, and cleaning the second liquid storage chamber 211. This improves the ease of use and cleanliness of the device, ensuring that users can always obtain a clean second liquid storage chamber 211.

[0080] The outer wall of the second liquid storage chamber 211 corresponding to the liquid heating container 210 is at least partially transparent and visible, so that the user can observe the heating situation in the second liquid storage chamber, thus realizing heating visualization.

[0081] Reference Figure 1 According to one embodiment of the present invention, the liquid heating assembly 200 further includes a mechanical water valve 270, which is located at the hot water outlet of the liquid heating container 210. The mechanical water valve is suitable for controlling the connection and disconnection between the drinking water passage 230 and the liquid heating container 210 when the liquid heating container 210 is connected or separated from the seat 220.

[0082] It is understood that, through the setting of the mechanical water valve 270, this embodiment ensures that the drinking water passage 230 is automatically closed or opened when the liquid heating container 210 is connected to or separated from the seat 220, thereby avoiding the risk of hot water leakage.

[0083] Specifically, when the liquid heating container 210 is placed on the base 220, the mechanical water valve 270 receives a connection signal and opens the drinking water passage 230, allowing hot water to flow through. When the liquid heating container 210 is removed from the base 220, the mechanical water valve 270 receives a disconnection signal and closes the drinking water passage 230, preventing hot water from flowing out. This prevents accidental hot water leakage when moving or cleaning the liquid heating container 210.

[0084] It should be noted that the mechanical water valve 270 can be automatically controlled by the control system. When a change in the connection status between the liquid heating container 210 and the seat 220 is detected, the drinking water passage 230 will be automatically opened or closed. Alternatively, the opening or closing of the drinking water passage 230 can be controlled by manually operating the solenoid valve assembly.

[0085] Reference Figure 1 According to one embodiment of the present invention, the liquid heating assembly 200 further includes an electrical coupling connector 280, which is respectively disposed on the liquid heating container 210 and the base 220 to realize the electrical connection between the liquid heating container 210 and the base 220.

[0086] When the liquid heating container 210 is removed from the base 220, the electrical coupling connector 280 disconnects, severing the electrical connection between the liquid heating container 210 and the base 220.

[0087] Reference Figure 1 According to one embodiment of the present invention, the liquid heating device 10 further includes an electronic control component 400, which is communicatively connected to the water tank component 100 and the liquid heating component 200.

[0088] It is understood that in this embodiment, the electronic control component 400 is used to receive user commands and coordinate the operation of various components according to the commands to ensure that the device can operate according to the user's needs. Through the centralized management and coordinated control of the electronic control component 400, the heating and cooling processes are automated and intelligent, improving the user experience and the efficiency of the device.

[0089] The electronic control component 400 can obtain the temperature of the cold water in the first liquid storage chamber 111 through the second temperature measuring component 170. Based on the temperature difference between the cold water in the first liquid storage chamber 111 and the hot water in the second liquid storage chamber 211, the electronic control component 400 can adjust the flow rates of the first water pump component 250 and the second water pump component 160 to regulate the heat exchange efficiency.

[0090] The electronic control component 400 can obtain the temperature of the liquid medium in the second liquid storage chamber 211 through the first temperature sensing component 260, and control the start and stop of the heating component according to the target temperature set by the user. At the same time, the electronic control component 400 can control the first water pump component 250 and the second water pump component 160 to achieve selective flow of hot water at different temperatures.

[0091] This implementation achieves automated control of the heating and cooling processes through the setting of the electronic control component 400, thereby improving the intelligence level of the device.

[0092] Reference Figure 2 In one embodiment, the liquid heating device 10 further includes a water replenishment passage 140, which connects the first liquid storage chamber 111 and the second liquid storage chamber 211. The main function of the water replenishment passage 140 is to enable automatic water replenishment to the second liquid storage chamber 211. When the water level in the second liquid storage chamber 211 drops to a certain level, the water replenishment passage 140 automatically opens, allowing water from the first liquid storage chamber 111 to flow into the second liquid storage chamber 211 for replenishment. This reduces the number of times the user needs to manually add water and improves ease of use.

[0093] Reference Figure 2 According to one embodiment of the present invention, the inlet end of the water replenishment passage 140 is connected to the first liquid storage chamber 111 through the circulating water passage 130, and the outlet end of the water replenishment passage 140 is connected to the second liquid storage chamber 211 through the drinking water passage 230.

[0094] It is understood that in this embodiment, the water replenishment passage 140 is indirectly connected to the first liquid storage chamber 111 and the second liquid storage chamber 211 through the circulating water passage 130 and the drinking water passage 230. This reduces the number of independent pipes, lowering the system's complexity and manufacturing cost. It also avoids the risk of leakage that might arise from excessive pipe connections. Furthermore, since the water replenishment passage 140 is connected to the circulating water passage 130 and the drinking water passage 230, the water replenishment function can be more easily integrated into the overall system's control logic. Through a unified control system, precise control and monitoring of the water replenishment process can be achieved, thereby improving the system's operating efficiency and stability. Simultaneously, in terms of maintenance, since the water replenishment passage 140 is connected to other passages, overall inspection and repair can be performed more conveniently, reducing maintenance costs and time.

[0095] Reference Figure 2 According to one embodiment of the present invention, the liquid heating device 10 includes a first solenoid valve assembly 150, and the water inlet of the water supply passage 140 is connected to the circulating water passage 130 through the first solenoid valve assembly 150.

[0096] It is understood that in this embodiment, the opening and closing of the water supply passage 140 and the circulating water passage 130 can be conveniently controlled by setting the first solenoid valve assembly 150; at the same time, by controlling the opening and closing state of the first solenoid valve assembly, the flow rate of the water supply passage 140 can be precisely adjusted to ensure that an appropriate amount of water is added to the second liquid storage chamber 211 when needed, while avoiding over-watering or under-watering, which helps to improve the stability and efficiency of the system.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
