Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an electric water bottle that cools down quickly. Background Technology
[0002] Electric water heaters, as convenient drinking water devices, have become mainstream appliances for meeting daily hot water needs due to their multi-functionality, integrating boiling, heat preservation, and reboiling. To ensure users can quickly obtain drinkable water, electric water heaters are equipped with a cooling function. However, currently, electric water heaters typically use fans to cool the liquid storage chamber, resulting in low cooling efficiency and a relatively long waiting time for boiling water to cool to a suitable temperature. Utility Model Content
[0003] To address the aforementioned technical problem of low cooling efficiency, this invention provides an electric water bottle with rapid cooling efficiency, enabling customers to quickly obtain water at a suitable drinking temperature.
[0004] The specific technical solution of this utility model is as follows: an electric hot water bottle with rapid cooling includes a bottle body with a first water outlet, a liquid storage chamber, a cooling chamber, a driving device, a heating device for heating the liquid storage chamber, and a cooling device for cooling the cooling chamber. The liquid storage chamber has a water outlet, and the cooling chamber has a water inlet and a second water outlet. The water outlet and the water inlet are connected through a cooling channel, and the second water outlet is connected to the first water outlet. The driving device is located in the cooling channel 13 to drive the liquid in the liquid storage chamber to be discharged from the water outlet into the cooling chamber.
[0005] In the aforementioned electric water bottle, the heating and cooling functions are separated through a dual-cavity structure. The liquid storage cavity is used for heating and storing hot water, while the cooling cavity serves as an independent cooling space. The driving device drives the liquid in the liquid storage cavity to be discharged from the water outlet into the cooling cavity. The cooling device focuses its action on the hot water in the cooling cavity to be cooled, eliminating the need to overcome a large amount of heat from the water as in traditional single-cavity systems. This reduces the amount of heat dissipation required for cooling, achieving a rapid cooling effect with higher cooling efficiency. Users can quickly obtain suitable drinking water through the first water outlet.
[0006] Optionally, the cooling device is located on the side of the cooling chamber away from the liquid storage chamber, and the second water outlet is located on the side close to the cooling device.
[0007] In the above technical solution, the heat of the liquid storage chamber will affect the cooling efficiency. This design avoids the heat of the cooling device and the liquid storage chamber from interfering with each other. The second outlet is located on the side close to the cooling device, so that the discharged liquid is directly cooled by the cooling device and has a lower temperature.
[0008] Optionally, the bottom surface of the cooling chamber is higher than the bottom surface of the liquid storage chamber, and the cooling range of the cooling device is greater than the height of the cooling chamber in the vertical direction. The cooling channel includes an inlet section connected to the water outlet and a cooling section connected to the water inlet. The drive device 12 is connected between the inlet section 5 and the cooling section 4. The cooling section is vertically arranged, and its cooling range can cover the cooling chamber and the cooling section, so as to realize the synchronous cooling of the liquid in the cooling chamber and the liquid flowing through the cooling section.
[0009] In the above technical solution, the cooling device can cool the cooling section and the cooling chamber at the same time. The hot water in the cooling section is pre-cooled by the cooling device to remove some heat in advance, and then enters the cooling chamber for final cooling. The cooling time of the hot water is greatly shortened under the dual cooling effect, which improves the cooling efficiency.
[0010] Optionally, the water inlet is located at the bottom of the cooling chamber and on one side near the cooling device, and the cooling section has a serpentine curved structure.
[0011] In the above technical solution, the height difference between the cooling chamber and the liquid storage chamber allows the bottom of the cooling chamber to have space to accommodate the cooling section. The cooling section extends fully in the bottom area of the cooling chamber. By increasing the extension length and the number of bends of the tube, the heat exchange path is extended, thereby improving the cooling efficiency.
[0012] Optionally, the water inlet section extends horizontally from the connection point with the water outlet section to the bottom of the cooling chamber.
[0013] In the above technical solution, the horizontal setting of the water inlet section saves the length of the pipeline. At the same time, when the hot water flows horizontally under the drive device, it does not need to overcome additional gravitational potential energy or the resistance caused by the inclination of the flow channel, so that the hot water can be delivered smoothly.
[0014] Optionally, the diameter of the cooling section is larger than the diameter of the water inlet section.
[0015] In the above technical solution, by increasing the diameter of the cooling section pipe, reducing the water flow rate in the cooling section, and expanding the outer surface area of the cooling section, the heat exchange capacity is increased and the heat exchange time is extended, thereby improving the cooling efficiency.
[0016] Optionally, the water outlet includes a mounting base, a filter device, and a filtrate receiving part. The filter device includes an inlet end communicating with the liquid storage chamber and an outlet end communicating with the filtrate receiving part. The outlet end is inserted into the mounting base and sealed to its inner wall. One end of the filtrate receiving part is inserted into the mounting base, and the other end is connected to the cooling channel.
[0017] In the above technical solution, the liquid storage chamber of the electric water bottle stores water for a long time and needs to be heated repeatedly, which can easily breed bacteria or accumulate various substances that affect drinking water safety. The filter device is set up to force all the liquid flowing out of the storage chamber to pass through the filter material of the filter device before it can continue to flow downstream, ensuring the hygiene and safety of the filtrate. The filtrate is first pre-cooled by the cooling section and then finally cooled by the cooling chamber, and finally discharged in a clean state with a suitable temperature.
[0018] Optionally, the water outlet extends downward from the bottom of the liquid storage chamber, allowing the liquid in the liquid storage chamber to flow to the water outlet by gravity.
[0019] In the above technical solution, the liquid in the storage chamber can flow naturally to the bottom by gravity, ensuring that the liquid flows continuously and stably into the outlet, reducing the pump drive load, and even if there is little liquid left in the chamber, the liquid can be completely discharged.
[0020] Optionally, the water inlet is located at the bottom of the cooling chamber, and the second water outlet is located at the top of the cooling chamber.
[0021] In the above technical solution, the water inlet is located at the bottom of the cooling chamber and the second water outlet is located at the top of the cooling chamber, so that there is a large distance difference between the two, which reduces the risk of uncooled liquid entering the water inlet and ensures the stability of the outlet water temperature; in addition, when the liquid enters from the bottom water inlet, it can avoid the water flow directly impacting the chamber wall and generating noise.
[0022] Optionally, the cooling device is a fan, with a vent on the side wall of the bottle, the fan's air inlet facing the vent, and the air outlet facing the cooling chamber.
[0023] In the above technical solutions, compared with water cooling, air cooling is not limited by the pipeline laying range. The cold air blown out by the fan can simultaneously wrap the outer wall of the cooling cavity and the cooling section pipeline. It has a simple structure, low cost and large cooling range.
[0024] Compared with the prior art, the present invention has at least the following advantages: The present invention achieves separation of heating and cooling functions through a dual-cavity structure. The liquid storage cavity is used for heating and storing hot water, while the cooling cavity serves as an independent cooling space. The driving device drives the liquid in the liquid storage cavity to be discharged from the water outlet into the cooling cavity. The cooling device focuses on the hot water to be cooled in the cooling cavity and cooling channel. Unlike the traditional single-cavity system, it does not need to overcome a large amount of water heat, thus reducing the heat dissipation required for cooling and achieving a rapid cooling effect. The cooling efficiency is higher, and users can quickly obtain suitable drinking water through the first water outlet. Attached Figure Description

[0027] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.
[0028] Example 1 Reference Figure 1 As shown, this utility model provides a fast-cooling electric water bottle, including a bottle body. The upper part of the bottle body is provided with a control module and a first water outlet 1 for draining water to the outside. The bottle body is provided with a liquid storage chamber 2, a cooling chamber 3, a drive device 12, a heating device for heating the liquid storage chamber 2, and a cooling device 8 for cooling the cooling chamber 3. The drive device 12, the heating device, and the cooling device 8 are electrically connected to the control module. The capacity of the liquid storage chamber 2 is larger than that of the cooling chamber 3. The lower end of the liquid storage chamber 2 is provided with a water outlet 14. The lower end of the cooling chamber 3 is provided with a water inlet 7, and the upper end is provided with a second water outlet 6. The water outlet 14 and the water inlet 7 are connected through a cooling channel 13. The second water outlet 6 is connected to the first water outlet 1. The drive device 12 is located in the cooling channel 13 to drive the liquid in the liquid storage chamber 2 to be discharged from the water outlet 14 into the cooling chamber 3.
[0029] It should be noted that this utility model does not limit the type of drive device 12. Any existing drive structure that can achieve the function of "transporting the liquid in the storage chamber 2 to the cooling chamber 3" falls within the protection scope of this utility model. In this embodiment, the drive device 12 is preferably a water pump, which can not only drive hot water to flow steadily into the cooling chamber 3 along the cooling channel 13 through power output, providing a continuous fluid source for the pre-cooling of the cooling section 4 and the final cooling of the cooling chamber 3, but also has an anti-backflow function, which can effectively prevent the cooled liquid in the cooling chamber 3 from flowing back to the storage chamber 2.
[0030] In the aforementioned electric water bottle, the heating and cooling functions are separated through a dual-cavity structure. The liquid storage cavity 2 is used for heating and storing hot water, while the cooling cavity 3 serves as an independent cooling space. The driving device 12 drives the liquid in the liquid storage cavity 2 to be discharged from the water outlet 14 into the cooling cavity 3. The cooling device 8 focuses on the hot water in the cooling cavity 3 to be cooled. Unlike traditional single-cavity systems, it does not need to overcome a large amount of water heat, thus reducing the amount of heat dissipation required for cooling and achieving a rapid cooling effect. The cooling efficiency is higher, and users can quickly obtain suitable drinking water through the first water outlet 1.
[0031] In this embodiment, the cooling device 8 is a fan. A vent is provided on the side wall of the bottle, and a control module is located on the upper part of the bottle. The fan's air inlet faces the vent, and its air outlet faces the cooling chamber 3. The fan is electrically connected to the control module, and its start and stop are controlled by inputting commands to the control module. Cooling air can be discharged in various ways. In one embodiment, a removable cap is provided at the bottom of the bottle to facilitate the assembly and maintenance of internal components. A structural gap exists between the cap and the bottom of the bottle, serving as a cooling air discharge channel. In another embodiment, an air outlet is provided on the bottle to discharge the cooled air after heat exchange. Compared to water cooling, air cooling is not limited by the piping layout. The cold air blown by the fan can simultaneously envelop the outer wall of the cooling chamber 3 and the cooling section 4 piping, resulting in a simple structure, low cost, and a large cooling range.
[0032] The control module integrates a temperature detection device connected to the cooling chamber 3. This device collects real-time temperature data of the water in the cooling chamber 3 and transmits it to the control module. When the water temperature in the cooling chamber 3 drops to a preset target temperature, the control module immediately sends a signal to cut off the fan power, automatically shutting down the fan. This not only avoids energy waste caused by the fan continuing to run after the water temperature reaches the target, but also prevents the water in the cooling chamber 3 from deviating from the target temperature due to excessive cooling, thus affecting the drinking experience. This invention does not limit the type of temperature detection device; any existing temperature detection device capable of achieving the above functions falls within the protection scope of this invention.
[0033] Taking the water boiling process as an example, the working process of this electric water bottle is as follows: raw water is filled into the storage chamber 2, the control module controls the heating device to start and heat the storage chamber 2. After the water boiling is completed, when the user triggers the cooling water demand, the control module controls the water pump to start, and hot water enters the cooling chamber 3 from the water outlet 14. The control module controls the fan to start and cool the cooling chamber 3. After the water in the cooling chamber 3 drops to the preset temperature, the fan is turned off, and the user can obtain drinking water through the first water outlet 1.
[0034] like Figure 1 As shown, the cooling device 8 is located on the side of the cooling chamber 3 away from the liquid storage chamber 2, and the second outlet 6 is located on the side closer to the cooling device 8. The liquid storage chamber 2 is used for heating and storing hot water, and its heat will affect the cooling efficiency. This design avoids mutual interference between the cooling device 8 and the liquid storage chamber 2. The second outlet 6 is located on the side closer to the cooling device 8, so that the discharged liquid is directly cooled by the cooling device 8 and has a lower temperature.
[0035] To avoid unstable water temperature at the first outlet 1, such as Figure 1As shown, the inlet 7 is located at the bottom of the cooling chamber 3, and the second outlet 6 is located at the top of the cooling chamber 3. Positioning the inlet 7 at the bottom and the outlet 6 at the top creates a significant distance difference between them, reducing the risk of uncooled liquid entering the inlet 7 and ensuring stable outlet water temperature. Furthermore, when liquid enters from the bottom inlet 7, it avoids direct impact on the chamber wall, preventing noise. The position of the inlet 7 relative to the bottom of the cooling chamber 3 is not limited; it can be positioned approximately diagonally opposite to the second outlet 6, or on the same side as the second outlet 6.
[0036] To increase the sealing of the water flow path, sealing rings can be installed at the connection ends of the cooling channel 13 with the water outlet 14 and the water inlet 7.
[0037] In a preferred embodiment of this utility model, such as Figure 1 As shown, the top surface of the cooling chamber 3 is flush with the top surface of the liquid storage chamber 2, and the bottom surface of the cooling chamber 3 is higher than the bottom surface of the liquid storage chamber 2. The cooling range of the cooling device 8 is greater than the height of the cooling chamber 3 in the vertical direction. The cooling channel 13 includes an inlet section 5 connected to the water outlet 14 and a cooling section 4 connected to the water inlet 7. The drive device 12 is connected between the inlet section 5 and the cooling section 4. The cooling section 4 is vertically arranged. The cooling range of the cooling device 8 can cover both the cooling chamber 3 and the cooling section 4, realizing the simultaneous cooling of the liquid in the cooling chamber 3 and the liquid flowing through the cooling section 4. The cooling device 8 can cool both the cooling section 4 and the cooling chamber 3 at the same time. The hot water in the cooling section 4 is pre-cooled by the cooling device 8 to remove some heat in advance, and then enters the cooling chamber 3 for final cooling. Under the dual cooling effect, the cooling time of the hot water is greatly shortened, improving the cooling efficiency. Figure 1 This is only a schematic diagram. Some of the connecting pipes of the cooling pipe are obscured by the structure and are not complete physical structures. Although it cannot directly show the connection relationship between the drive device 12 and the liquid storage chamber 2 and the cooling chamber 3, it is explained here that: In this embodiment, the drive device 12 is sealed to the water outlet 14 of the liquid storage chamber 2 and the water inlet 7 of the cooling chamber 3 through rubber hoses. This part of the rubber hose constitutes a part of the cooling channel 13, and together they form a complete closed flow path from the liquid storage chamber 2 to the cooling chamber 3.
[0038] Furthermore, such as Figure 1 As shown, the water inlet 7 is located at the bottom of the cooling chamber 3 and on the side close to the cooling device 8. The cooling section 4 has a serpentine bend structure with an arc transition at the corner. The height difference between the cooling chamber 3 and the liquid storage chamber 2 provides space for the cooling section 4 at the bottom of the cooling chamber 3. The cooling section 4 extends fully in the bottom area of the cooling chamber 3. By increasing the extension length and the number of bends of the tube, the heat exchange path is lengthened, thereby improving the cooling efficiency.
[0039] Furthermore, such as Figure 1As shown, the water inlet section 5 extends horizontally from its connection point with the water outlet section 14 to the bottom of the cooling chamber 3. The horizontal arrangement of the water inlet section 5 saves on pipe length. Simultaneously, when the hot water flows horizontally under the drive device 12, it does not need to overcome additional gravitational potential energy or resistance caused by the inclined flow channel, allowing for smooth hot water delivery. It should be noted that in the cooling channel 13, the water inlet section 5 and the cooling section 4 can transition via an angle or an arc.
[0040] To further improve the efficiency of hot water cooling, such as Figure 1 As shown, the diameter of the cooling section 4 is larger than that of the water inlet section 5. By increasing the diameter of the cooling section 4, the water flow rate inside the cooling section 4 is reduced and the outer surface area of the cooling section 4 is expanded, thereby increasing the heat exchange capacity and extending the heat exchange time, and improving the cooling efficiency.
[0041] Because the water storage chamber 2 of an electric kettle stores water for a long time and needs to be repeatedly heated, it is prone to bacterial growth or accumulation of various substances that may affect drinking water safety. To ensure drinking water hygiene and safety, the water outlet 14 includes a mounting base, a filter device 9, and a filtrate receiving part 11. The filter device 9 includes an inlet end communicating with the storage chamber 2 and an outlet end communicating with the filtrate receiving part 11. The outlet end is inserted into the mounting base and sealed to its inner wall. One end of the filtrate receiving part 11 is inserted into the mounting base, and the other end is connected to the cooling channel. The filter device 9 is equipped with a cotton filter element and an activated carbon composite filter element. The hot water in the storage chamber 2 flows to the bottom of the water outlet 14 due to gravity. The filter device 9 forces all liquid flowing out of the storage chamber 2 to pass through the filter material of the filter device 9 before continuing to flow downstream, ensuring the hygiene and safety of the filtrate. The filtrate is first pre-cooled by the cooling section 4 and then finally cooled by the cooling chamber 3, and finally discharged in a clean state at a suitable temperature. Understandably, the mounting base 10 can also be installed in the cooling channel 13 or the water outlet path.
[0042] In embodiments where the filter device 9 is not provided, the water outlet 14 is presented as an opening at the bottom of the liquid storage chamber 2.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
