Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electric water bottles, and more specifically, to an instant electric water bottle. Background Technology
[0002] Currently, people are paying more attention to the health of their drinking water, and electric kettles have become a common household item and an essential product in modern life. Common electric kettles mainly operate in two modes: one mode boils the water to a boil for sterilization, but this mode cannot provide hot water to the user at any time, resulting in a poor user experience in winter; the other mode boils the water, cools it to the set temperature, and then keeps it warm. If the user needs hotter water later, the kettle will continue to heat the water to the target temperature.
[0003] In the prior art, such as Chinese patent CN108814279A, an instant electric kettle with a water purification function is disclosed. Its structure includes: an electric kettle body, a water storage body, a first inner shell embedded inside the water storage body, a water storage chamber inside the first inner shell, a spout welded to the left side of the water storage body, the spout being detachably connected to a spout cap on the top, a handle connected to the right side of the water storage body, a heating switch on the top of the handle, and the water storage body being connected to the top cap via a bearing. The water storage body is connected to a heating element. This type of electric kettle can achieve instant heating without continuously turning on the heating device. However, in the process of providing hot water to the user, even if the user only needs a small amount of hot water, all the water in the electric kettle needs to be heated as a whole, resulting in high energy consumption. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that require heating all the water in the kettle as a whole, resulting in high energy consumption. This invention provides an instant electric water bottle that only needs to heat the amount of water required by the user to achieve both heat preservation and instant hot water dispensing functions, thereby reducing energy consumption and increasing the water dispensing speed.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] An instant electric water heater is provided, comprising a shell, a heating element, an inner liner assembly for holding water, an instant heating element, and a water pipe. The inner liner assembly is disposed within the shell, and the shell is provided with a water outlet. One end of the water pipe is connected to the inner liner assembly, and the other end is connected to the water outlet. The heating element is connected to the inner liner assembly and is used to heat the water contained in the inner liner assembly. The instant heating element is disposed in the water pipe area near the water outlet and is used to heat the water in the water pipe near the water outlet.
[0007] This invention relates to an instant electric water bottle. A heating element heats the water inside the inner tank to its boiling point for sterilization. The boiled water flows through the water pipe to the instant heating element and finally exits from the spout. The remaining hot water is stored in the inner tank for insulation. Positioning the instant heating element near the spout reduces heat loss as the water flows to the spout. When the user requires water at a temperature higher than the water temperature inside the inner tank, the instant heating element is activated to rapidly heat the water flowing through it. Heating only the required volume of water, rather than heating the entire inner tank, reduces energy consumption, increases water flow speed, and optimizes the user experience.
[0008] Furthermore, the heating element is a heating plate, which is disposed at the bottom of the inner tank assembly. The heating plate, located at the bottom of the inner tank assembly, enables rapid heating of the water within the inner tank assembly, while ensuring uniform heating and preventing localized overheating.
[0009] Furthermore, it also includes a water pump and a water valve for controlling the water flow. One end of the water pump is connected to the inner tank assembly, and the other end is connected to the instant heating assembly. The water valve connects the water pump and the inner tank assembly. When the user needs hot water, the water valve at the bottom of the inner tank assembly is opened, and the water pump draws water from the inner tank assembly and pumps it into the instant heating assembly. The water valve controls the flow rate in the water pump and prevents backflow. The water pump provides power for the water flow, and the two work together to enable the electric water heater to provide stable and rapid hot water.
[0010] Furthermore, the water pipeline includes a first water pipe, a second water pipe, and a third water pipe. The water valve and the water pump are connected via the first water pipe, the water pump and the instant heating component are connected via the first water pipe, and the instant heating component and the water outlet are connected via the third water pipe. Water in the inner tank assembly flows out from the water valve, through the first water pipe to the water pump, and after being pressurized by the water pump, it flows into the instant heating component through the second water pipe, and finally flows into the water outlet through the third water pipe to provide hot water to the user.
[0011] Furthermore, it also includes a float assembly for detecting the water level of the inner tank assembly. The water pipeline also includes a fourth water pipe, and the float assembly is connected to the first water pipe through the fourth water pipe. The float assembly is also signal-connected to the instant heating assembly. The float assembly is connected to the first water pipe through the fourth water pipe, and the first water pipe is connected to the inner tank assembly, thus forming a communicating vessel between the float assembly and the inner tank assembly. The float assembly can detect the water level of the inner tank assembly and adjust the working state of the instant heating assembly according to the water level in the inner tank assembly, thereby preventing dry burning and protecting the instant heating assembly.
[0012] Furthermore, the float assembly includes a receiving cavity, a float with a magnet inside, and a float rod with a reed switch inside. The receiving cavity is connected to the fourth water pipe, the float rod is fixed inside the receiving cavity, and the float is sleeved on the float rod and movably connected to the float rod. When the water level in the inner tank assembly is high, water flows through the fourth water pipe to fill the receiving cavity, the float rises along the float rod, and the magnet approaches the reed switch, keeping the circuit of the instant heating component connected and enabling normal heating. When the water level is low, as the float falls along the float rod, the magnet moves away from the reed switch, disconnecting the working circuit of the instant heating component and preventing dry burning.
[0013] Furthermore, the system also includes a control panel disposed on the surface of the housing and a temperature sensor disposed at the bottom of the inner tank assembly, the control panel being signal-connected to the temperature sensor. The temperature sensor detects the water temperature in the inner tank assembly in real time and displays it through the control panel, thereby providing feedback to the user so that the user can be aware of the internal water temperature at any time.
[0014] Furthermore, the instant heating component is signal-connected to the control panel. The user selects the desired outlet water temperature on the control panel. When the outlet water temperature is higher than the water temperature in the inner tank assembly, the instant heating component is activated to heat the passing water flow to the desired outlet water temperature before supplying it to the user from the outlet.
[0015] Furthermore, it also includes a thermostat located at the bottom of the inner tank assembly. The thermostat, temperature sensor, and heating element are all connected to the control panel via signal transmission. The temperature sensor detects the water temperature in the inner tank assembly and transmits the water temperature data to the control panel. When the water temperature exceeds the set value, the control panel sends a power-off protection signal to the thermostat, which disconnects the working circuit of the heating element, stopping heating and thus preventing overheating that could lead to energy waste or damage to components.
[0016] Furthermore, the inner liner assembly is detachably connected to the outer shell. The inner liner assembly can be removed from the outer shell, making it convenient for users to remove and clean after prolonged use, and preventing scale buildup in the inner liner assembly.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. When achieving the functions of heat preservation and instant hot water output, only the amount of water required by the user needs to be heated, which reduces energy consumption and increases the water output speed.
[0019] 2. The instant heating element and the heating element are protected by a float assembly and a thermostat to prevent dry burning when the water level is insufficient;
[0020] 3. The instant heating component heats only the amount of water needed by the user, which can provide hot water quickly and reduce overall energy consumption. Attached Figure Description

[0029] Example 1
[0030] This embodiment is a first embodiment of an instant electric water bottle, including a shell 100, a heating element 210, an inner liner assembly 200 for holding water, an instant heating element 300, and a water pipe. The inner liner assembly 200 is disposed inside the shell 100, and the shell 100 is provided with a water outlet 110. One end of the water pipe is connected to the inner liner assembly 200, and the other end is connected to the water outlet 110. The heating element 210 is connected to the inner liner assembly 200 and is used to heat the water contained in the inner liner assembly 200. The instant heating element 300 is disposed in the water pipe area near the water outlet 110 and is used to heat the water in the water pipe near the water outlet 110.
[0031] like Figure 1 , Figure 2 As shown, in this embodiment, the instant electric water bottle heats water to its boiling point through the heating element 210 in the inner tank assembly 200 for sterilization. The boiled water flows through the instant heating element 300 via the water pipe and finally flows out from the spout 110. The un-flowed hot water is stored in the inner tank assembly 200 for heat preservation. Positioning the instant heating element 300 near the spout 110 on the water pipe reduces heat loss as the water flows towards the spout 110. When the user requires a water temperature higher than the water temperature in the inner tank assembly 200, the instant heating element 300 is activated to rapidly heat the water flowing through it. During the heating process, only the amount of water required by the user is heated, rather than heating the entire amount of water in the inner tank assembly 200. This reduces energy consumption, increases water flow speed, and optimizes the user experience.
[0032] The heating element 210 is a heating plate, which is located at the bottom of the inner liner assembly 200. For example... Figure 1As shown, the heating plate is located at the bottom of the inner tank assembly 200, enabling rapid and uniform heating of the water within the inner tank assembly 200, preventing localized overheating. In this embodiment, the heating plate has a large heating area and heats up quickly. It can be fixed to the bottom inner side of the inner tank assembly 200 by brazing, a simple process with fast assembly speed. The heating element 210 can also be located on the side of the inner tank assembly 200, providing surround heating and increasing the heating rate through a larger heating area. In this embodiment, the heating plate can also be mounted on the shell 100 and coupled to the inner tank assembly 200.
[0033] The instant electric water heater in this embodiment also includes a water pump 400 and a water valve 500 for controlling the water flow. One end of the water pump 400 is connected to the inner tank assembly 200, and the other end is connected to the instant heating assembly 300. The water valve 500 connects the water pump 400 and the inner tank assembly 200. When the user needs hot water, the water valve 500 at the bottom of the inner tank assembly 200 is opened, and the water pump 400 draws water from the inner tank assembly 200 and pumps it into the instant heating assembly 300. The water valve 500 controls the flow rate in the water pump 400 and prevents backflow. The water pump 400 provides power for the water flow, and the two work together to enable the electric water heater to provide stable and rapid hot water. In this embodiment, the instant heating assembly 300 can be a surround-type instant heating tube, with a water pipe inside for water flow and a heating tube surrounding the outside of the water pipe, which rapidly heats the water flowing inside.
[0034] like Figure 3 , Figure 4 As shown, the water piping includes a first water pipe 610, a second water pipe 610, and a third water pipe 630. The water valve 500 is connected to the water pump 400 via the first water pipe 610. The water pump 400 is connected to the instant heating element 300 via the second water pipe 620. The instant heating element 300 is connected to the water outlet 110 via the third water pipe 630. Water in the inner tank assembly 200 flows out from the water valve 500, passes through the first water pipe 610 to the water pump 400, and after the water pump 400 increases the pressure, it flows into the instant heating element 300 through the second water pipe 620, and finally flows into the water outlet 110 through the third water pipe 630, providing hot water to the user. Figure 1As shown, in this embodiment, the water valve 500 is located at the bottom of the inner tank assembly 200. The height of the water pump 400 is greater than the height of the water valve 500. The first water pipe 610 has an approximately U-shaped shape, and the length of the water pipe connected to the water pump 400 is greater than the length of the water pipe connected to the water valve 500. To increase the instant heating efficiency and improve the heating speed, the length of the instant heating component 300 should be chosen to be as long as possible, so that the height of the inlet of the instant heating component 300 is lower than the height of the outlet of the water pump 400. An L-shaped second water pipe 620 is used to connect the water pump 400 and the instant heating component 300. The specific shape of the third water pipe 630 can be adjusted according to the relative position of the instant heating component 300 and the water outlet 110 to ensure that the water flows out smoothly.
[0035] The inner tank assembly 200 is detachably connected to the housing 100. The inner tank assembly 200 can be removed from the housing 100, making it convenient for users to remove and clean after long-term use, and preventing scale buildup in the inner tank assembly 200.
[0036] like Figure 5 As shown, the housing 100 in this embodiment also includes a base 130, a bottom cover 131, a rear cover 140, a panel 150, an outer shell 160, a middle ring 170, and a kettle lid 180. The bottom cover 131 is connected to the inner liner assembly 200 and is located at the bottom of the inner liner assembly 200. A locking part for fixing the position of the inner liner assembly 200 can be provided on the base 130. The inner liner assembly 200 is locked to the locking part to ensure that it will not shake during operation. The outer shell 160 is fitted onto the side of the inner liner assembly 200, protecting the structure of the inner liner assembly 200 and preventing the user from being burned by the high temperature of the inner liner assembly 200 during operation. The middle ring 170 is located at the top of the inner liner assembly 200 and has an internal cavity for accommodating the kettle lid 180. During use, the kettle lid 180 can be removed to directly add water to the inner liner assembly 200. The panel 150 is connected to the inner tank assembly 200, and an installation cavity is provided between the panel 150 and the inner tank assembly 200 for installing structures such as the instant heating assembly 300, water pump 400, float assembly 700, and water outlet 110.
[0037] The working principle of the instant electric water bottle in this embodiment is as follows: the water in the inner tank assembly 200 is heated to the boiling point by the heating element 210 for sterilization and disinfection. After boiling, the water passes through the instant heating element 300 and finally flows out from the water outlet 110. The hot water that does not flow out is stored in the inner tank assembly 200. When the water temperature required by the user is higher than the water temperature in the inner tank assembly 200, the instant heating element 300 is activated to quickly heat the water flowing through the instant heating element 300.
[0038] Example 2
[0039] This embodiment is a second embodiment of an instant electric water heater. This embodiment is similar to the first embodiment, except that it also includes a float assembly 700 for detecting the water level in the inner tank assembly 200. The water pipeline also includes a fourth water pipe 640. The float assembly 700 is connected to the first water pipe 610 through the fourth water pipe 640, and the float assembly 700 is electrically connected to the instant heating assembly 300. Figure 3 As shown, in this embodiment, the fourth water pipe 640 is L-shaped, with one end connected to the bottom of the float assembly 700 and the other end connected to the first water pipe 610, thereby connecting the inner tank assembly 200 and the float assembly 700 to form a communicating vessel between them. When the water level in the inner tank assembly 200 is high, water flows through the fourth water pipe 640 to fill the accommodating cavity 710, and the float 720 floats up along the float rod 730. The float assembly 700 controls the circuit of the instant heating assembly 300 to remain connected, enabling normal heating. When the water level is low and the float 720 falls along the float rod 730, the working circuit of the instant heating assembly 300 is disconnected to prevent dry burning.
[0040] The float assembly 700 includes a receiving cavity 710, a float 720 with a magnet inside, and a float rod 730 with a reed switch inside. The receiving cavity 710 is connected to the fourth water pipe 640. The float rod 730 is fixed inside the receiving cavity 710, and the float 720 is sleeved on the float rod 730 and movably connected to it. Figure 1 , Figure 3 As shown, when the water level in the inner tank assembly 200 is high, water flows through the fourth water pipe 640 to fill the accommodating cavity 710. The float 720 rises along the float rod 730. The float assembly 700 controls the circuit of the instant heating assembly 300 to remain connected, enabling normal heating. When the water level is low, and the float 720 falls along the float rod 730, the working circuit of the instant heating assembly 300 is disconnected to prevent dry burning. In this embodiment, the float 720 is equipped with a magnet, and the float rod 730 is equipped with a reed tube. The rise or fall of the float 720 can be controlled by the water level to determine whether there is a water shortage in the instant heating assembly 300. When the magnet is close to the reed switch, the circuit in the instant heating assembly 300 is connected, and heating can be performed; when the magnet is far away from the reed switch, the circuit is disconnected, and heating stops, thereby preventing dry burning.
[0041] The working principle of this embodiment of the instant electric water bottle is as follows: When the water level in the inner tank assembly 200 is high, the water flows through the fourth water pipe 640 to fill the accommodating cavity 710. The float 720 floats up along the float rod 730, and the magnet approaches the reed switch. The float assembly 700 controls the circuit of the instant heating assembly 300 to remain connected, so that it can heat normally. When the water level is low, the float 720 falls down along the float rod 730, the magnet moves away from the reed switch, and the working circuit of the instant heating assembly 300 is disconnected to avoid dry burning.
[0042] Example 3
[0043] This embodiment is the third embodiment of an instant electric water bottle. This embodiment is similar to Embodiment 1, except that it also includes a control panel 150 disposed on the surface of the housing 100 and a temperature sensor 810 disposed at the bottom of the inner liner assembly 200. The control panel 150 and the temperature sensor 810 are connected for signal transmission. Figure 2 , Figure 5 As shown, the temperature sensor 810 detects the water temperature in the inner tank assembly 200 in real time and displays it through the control panel 150, thereby providing feedback to the user so that the user can know the internal water temperature at any time.
[0044] The instant heating element 300 is connected to the control panel 150 via a signal. The user selects the desired outlet water temperature on the control panel 150. When the outlet water temperature is higher than the water temperature in the inner tank assembly 200, the instant heating element 300 is activated, heating the flowing water to the desired outlet temperature before supplying it to the user through the outlet spout 110. The user can also set the insulation temperature of the inner tank assembly 200 via the control panel 150. Through the cooperation of the temperature sensor 810 and the heating element, the water in the inner tank is maintained at the set temperature. When the water in the inner tank is in insulation mode, such as at 45℃, and the user needs 80℃ water, after selecting the temperature and corresponding water volume, the water valve 500 controls the water flow from the inner tank assembly 200. The water pump 400 draws 45℃ water and delivers it to the instant heating element 300, which heats the flowing 45℃ water to 80℃ before it flows out from the outlet spout 110.
[0045] The instant electric water bottle in this embodiment also includes a thermostat 820 located at the bottom of the inner tank assembly 200. The thermostat 820, temperature sensor 810, and heating element 210 are all connected to the control panel 150 via signal transmission. The temperature sensor 810 detects the water temperature in the inner tank assembly 200 and transmits the water temperature data to the control panel 150. When the water temperature exceeds the set value, the control panel 150 sends a power-off protection signal to the thermostat 820, which disconnects the working circuit of the heating element 210, stopping heating and thus avoiding energy waste or component damage due to overheating.
[0046] The working principle of this embodiment of the instant electric water bottle is as follows: the temperature sensor 810 detects the water temperature in the inner tank assembly 200 and transmits the water temperature data to the control panel 150. When the water temperature exceeds the set value, the control panel 150 sends a power-off protection signal to the thermostat 820, which disconnects the working circuit of the heating element 210.
[0047] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
