Description

Technical Field

[0001] The utility model relates to the technical field of electric kettles, and particularly relates to a water cooling device and an electric kettle. Background Art

[0002] An electric kettle is a common household appliance in every family life. The traditional electric kettle only has a single function of boiling water. If you want to make the boiled water reach a suitable drinking temperature, you can only let it cool naturally, which requires a long time to wait. If the kettle lid is opened for heat dissipation, dust in the air will fall into the water and pollute the boiled water, which is time-consuming and troublesome.

[0003] Therefore, with the development of technology, more and more electric kettles with a cooling function have emerged on the market. For example, the Chinese invention patent with the publication number CN201310621280.3 discloses a hot water kettle, which includes a hot water bottle shell, a water inlet and outlet arranged above the hot water bottle shell, an opening penetrating through the upper part of the hot water bottle shell, a bottle inner liner arranged inside the hot water bottle shell and connected thereto, a handle arranged outside the hot water bottle shell and connected thereto, a heat conducting plate arranged outside the bottle inner liner and connected thereto, a temperature sensor arranged inside the bottle inner liner and connected thereto, a fan arranged below the bottle inner liner, and a circuit control device arranged below the temperature sensor; the hot water kettle senses the temperature inside the bottle through the temperature sensor, so that the circuit control device can quickly heat or cool the water in the bottle.

[0043] Next, the embodiments of this specification will be described in detail.

[0044] Please refer to Figures 1 to 6 as shown in Figure 1 the structural and working water flow direction schematic diagram of a water cooling device of this application; Figure 2 the structural schematic diagram of the cooler of a water cooling device of this application; Figure 3 the structural schematic diagram of the main body of an electric kettle of this application; Figure 4 the structural schematic diagram of the kettle of an electric kettle of this application; Figure 5 the internal structural schematic diagram of an electric kettle of this application; Figure 6 the water flow direction schematic diagram when a user takes water from an electric kettle of this application.

[0045] As shown in the figure, in order to solve the problems of low cooling efficiency and slow cooling speed in the existing electric kettle, the present application provides a water cooling device for an electric kettle with a kettle. The water cooling device includes: a water inlet pipeline, a water pump 40, a water outlet pipeline, and a cooler. The cooler 10 has a cooling flow channel for water to flow through. The cooler 10 includes a cooler main body 13, and a three-way air guiding assembly 12 and a cooling fan 11 that are sequentially arranged adjacent to the outside of the cooler main body 13.

[0046] Preferably, the cooler 10 further includes a positioning bracket 14, which is convenient for relatively fixing the cooler main body 13, the three-way air guiding assembly 12, and the cooling fan 11.

[0047] Specifically, the water inlet pipeline is connected to the kettle to realize the water in the kettle being introduced into the cooler 10 for cooling. The water pump 40 is connected to the water inlet pipeline, and the water outlet pipeline is connected to the water pump 40 to realize pumping water from the kettle into the cooler 10 to supply water to the cooling flow channel of the cooler 10, or pumping water from the kettle into other components of the electric kettle. The cooler 10 is connected to the water outlet pipeline, so that the water can be transported back to the kettle through the water outlet pipeline after being cooled by the cooler 10. The three-way air guiding assembly 12 can direct the cold air blown out by the cooling fan 11 to both the cooler 10 and the outer wall of the kettle at the same time, so as to cool the water in the cooler 10 and the water in the kettle.

[0048] In an embodiment, the water inlet pipeline includes a first branch pipe 21, a first three-way solenoid valve 31, a second branch pipe 22, and a third branch pipe 23. The first three-way solenoid valve 31 is a three-way solenoid valve with two inlet ends and one outlet end. The first branch pipe 21 is connected to the kettle, the second branch pipe 22 is connected to the outlet end of the first three-way solenoid valve 31, the second branch pipe 22 is connected to the water pump 40, and the first branch pipe 21 and the third branch pipe 23 are respectively connected to the two inlet ends of the first three-way solenoid valve 31. Specifically, when the water in the kettle needs to be cooled, under the action of the water pump 40, the water enters the first three-way solenoid valve 31 from the kettle through the first branch pipe 21, and then flows into the second branch pipe 22, and is pumped into the cooler 10 by the water pump 40 for cooling.

[0049] Preferably, the third branch pipe 23 is an air inlet pipe for draining the residual water in the pipeline of the water cooling device. Specifically, in the working state of draining water from the pipeline, the inlet end of the first three-way valve connected to the first branch pipe 21 is closed, and the inlet end connected to the third branch pipe 23 is opened. Air enters the second branch pipe 22 from the third branch pipe 23 through the first three-way solenoid valve 31, and then squeezes the water in the pipeline out of the pipeline through the water pump 40 and the outlet pipeline.

[0050] In one embodiment, the cooler body 13 is made of stainless steel material. Since stainless steel material is very effective in regulating temperature, the cooler body 13 made of stainless steel material has a good cooling effect on water. And stainless steel material is non-polluting to water, resistant to low-degree acids and alkalis. Even as a container for storing water for a long time, it will not cause secondary pollution, ensuring the cleanliness of water quality. At the same time, the cooler body 13 made of stainless steel material has a long service life.

[0051] In one embodiment, the water outlet pipeline includes a first water pipe 51, a second three-way solenoid valve 32, a second water pipe 52 and a third water pipe 53. The second three-way solenoid valve 32 is a three-way solenoid valve with one water inlet end and two water outlet ends. The first water pipe 51 is connected to the water pump 40, the water inlet end of the second three-way solenoid valve 32 is connected to the first water pipe 51, the cooler 10 is connected to the second water pipe 52, and the second water pipe 52 and the third water pipe 53 are respectively connected to the two water outlet ends of the second three-way solenoid valve 32. Specifically, the second water pipe 52 is connected to the kettle, and the second water pipe 52 is used to transport the water in the cooler 10 to the kettle, realizing that the water can be circulated into the cooler 10 for cooling, improving the cooling efficiency of water and having a better cooling effect. And the third water pipe 53 is used to transport the water in the kettle to other places.

[0052] It should be noted that the three-way solenoid valve is mainly used to control the on / off or flow direction of the fluid. In an electric kettle, connecting the three-way solenoid valve to components such as a control circuit board that can receive input signals, process data, execute logical control, and drive the electric kettle to work can achieve automatic control of the flow direction or flow rate of the fluid.

[0053] This application also provides an electric kettle, which includes a kettle 60 and the above-mentioned water cooling device, and the water inlet pipeline of the water cooling device is connected to the kettle 60.

[0054] In one embodiment, the electric kettle further includes a main body 70. The water cooling device is arranged inside the main body 70. An air inlet opening 711 and two air outlet openings are provided on the outer wall of the main body 70. One of the air outlet openings is used for the heat of the cooler body 13 to dissipate from the inside of the main body 70, and the other air outlet opening 712 is used to direct the cold air blown by the cooling fan 11 to the outer wall of the kettle 60 to cool the water in the kettle 60. This way of using the cooling fan 11 to dissipate heat from the water flowing through the cooling body and the water remaining in the kettle 60 at the same time improves the cooling efficiency of water.

[0055] Preferably, the main body 70 has a water outlet opening 73 that can communicate with the third water pipe 53 of the water outlet pipeline. Through this water outlet opening 73, the water in the electric kettle can be transported out for the user to drink.

[0056] Preferably, the bottom of the main body 70 has a heat dissipation vent 74.

[0057] In one embodiment, the bottom of the kettle 60 has an upper coupler and a heating element electrically connected to the upper coupler; the main body 70 has a lower coupler 72 which can be electrically connected to the upper coupler. The lower coupler 72 can be connected to a power socket through a power cord to connect the lower coupler 72 to the power supply. When the upper coupler is connected to the lower coupler 72, the heating element can heat the water in the kettle 60. Preferably, the water inlet pipe passes through the lower coupler 72. When the kettle 60 is placed on the main body 70, the water inlet pipe is connected to the kettle 60 to pump the water in the kettle 60 into the cooler 10 for cooling, or to draw out the water in the kettle 60 for drinking.

[0058] In one embodiment, the interior of the main body 70 has a control circuit board and a water flow sensor. The water flow sensor is installed on the water outlet pipe and is electrically connected to the control circuit board so that the electric kettle can supply water to customers quantitatively.

[0059] It should be noted that the water flow sensor can detect the volume or mass of water flowing through the sensor, and the control circuit board is responsible for receiving input signals, processing data, controlling the operation of the device and output. In this application, the control circuit board is electrically connected to the water flow sensor, and the control circuit board can also be electrically connected to the water pump 40, two three-way solenoid valves, etc. The volume or mass of water flowing through the sensor detected by the water flow sensor is transmitted to the control circuit board in the form of a signal. The control circuit board can receive this signal and monitor the water output of the kettle 60. When the water output reaches the preset water output target, the control circuit board controls the water pump 40 to stop pumping water, and at the same time can also control the outlet end and the inlet end of the three-way solenoid valve to close to achieve quantitative water output for users.

[0060] Specifically, connect the water flow sensor to the control circuit board. After the user sets the water output of the electric kettle, the water pump 40 pumps the water in the kettle 60 into the water outlet pipe and outputs it through the third water pipe 53 for the user to drink. The water flow sensor detects the water volume flowing through the water outlet pipe. When the water volume reaches the water output set by the user, the water flow sensor transmits a signal to the control circuit board, and the circuit control board controls the electric kettle to stop discharging water, realizing the function of accurate quantitative water output of the electric kettle.

[0061] Preferably, the water flow sensor of the present application can also be used to detect whether there is water in the kettle 60. If there is no water, the sensor will send a signal to the control circuit, thereby avoiding heating the kettle 60 in a waterless state, preventing dry burning and damage, and thus preventing dangerous accidents from occurring.

[0062] Preferably, the water flow sensor of the present application can also indirectly determine the water level in the kettle 60 by detecting the water flow rate through the outlet pipeline. When the water in the kettle 60 reaches the set water level, the water flow sensor will send a signal to the control circuit, causing the kettle 60 to automatically cut off power and stop heating, which ensures that the water will not overflow or boil due to overheating, preventing dangerous accidents from occurring.

[0063] In this embodiment, a temperature sensor is also installed in the kettle 60, and the temperature sensor is electrically connected to the control circuit board to monitor the temperature of the water in the kettle 60.

[0064] Specifically, the user sets the required outlet water temperature in advance. After the water in the electric kettle is boiled, the water cooling device in the electric kettle starts to work to cool the water. When the temperature sensor detects that the water temperature in the kettle 60 reaches the outlet water temperature set by the user, the temperature sensor transmits a signal to the control circuit board, and the control circuit board controls the water cooling device to stop working, realizing that the electric kettle can accurately cool the water so that the user can set the outlet water temperature of the electric kettle according to their own needs.

[0065] Specifically, the temperature sensor can also detect the water temperature in the kettle 60. When the water temperature reaches the set heating temperature, the sensor will send a signal to the control circuit board to stop the heating element from heating. By monitoring the water temperature, the temperature sensor can prevent the water in the kettle 60 from boiling over or causing dry burning due to overheating, thus protecting the equipment and user safety.

[0066] Preferably, the temperature sensor can also detect the water temperature and maintain it at a set constant temperature state to ensure that the water remains at a constant temperature within the required time.

[0067] In this embodiment, the exterior of the main body 70 has a control panel, and the control panel is electrically connected to the control circuit board. The control panel provides an interface for the user to interact with the electric kettle and has the functions of displaying information and controlling the electric kettle. The user's input is transmitted to the control circuit board through the control panel to execute the corresponding control logic. Specifically, the user can control the electric kettle to heat or stop heating the water through the control panel, and can also control the water output and outlet water temperature of the electric kettle through the control panel. Correspondingly, the control panel can display relevant information about the electric kettle, such as the water output and the water temperature in the kettle 60.

[0068] In a preferred embodiment, the kettle 60 has a kettle cover, which includes a first cover 611 and a second cover 612, wherein the second cover 612 is placed in the first cover 611 and is movably connected to the first cover 611. The second cover 612 has a pressing mechanism and a lifting mechanism, which is connected to the pressing mechanism. The pressing mechanism is configured to allow the user to control the opening and closing of the second cover 612 by pressing, and the lifting mechanism can respond to the action of the pressing mechanism so that the second cover 612 moves between the open and closed positions. When the second cover 612 is in an open state, an opening is formed between the first cover 611 and the second cover 612 so that the water vapor in the kettle 60 is emitted through the opening. This can further improve the cooling efficiency of the water in the kettle 60.

[0069] In a specific embodiment, the user sets the water outlet temperature of the electric kettle through the control panel, and the control circuit board controls the heating element to boil the water in the kettle 60, or when the water has been boiled, on the one hand, the control circuit board controls the water pump 40 to pump water into the cooler 10 for cooling and then flows back to the kettle 60, and on the other hand, the cold air blown out by the cooling fan 11 in the cooler 10 is sent to the outer wall of the kettle 60 through the three-way air guide component 12, thereby accelerating the cooling of the water. Afterwards, the temperature sensor is used to detect whether the water temperature reaches the water outlet temperature preset by the user. If the water temperature is still higher than the set water outlet temperature, the control circuit board continues to control the water cooling device to cool the water until the temperature sensor detects that the temperature of the water in the kettle 60 reaches the water outlet temperature set by the user. The control circuit board controls the water outlet end of the second three-way solenoid valve 32 connected to the third water pipe 53 to open, and closes the water outlet end of the second three-way solenoid valve 32 connected to the second water pipe 52. At the same time, the inlet end of the first three-way solenoid valve 31 connected to the first branch pipe 21 is opened, and the outlet end of the first three-way solenoid valve connected to the second branch pipe is opened, and the inlet end of the first three-way solenoid valve 31 connected to the third branch pipe 23 is closed, so that the electric kettle supplies water to the user according to the water outlet temperature set by the user. On the other hand, when the water in the kettle 60 reaches the temperature set by the user, the electric kettle enters the keep-warm state. When the temperature sensor detects that the temperature in the kettle 60 drops below the water outlet temperature set by the user, the control circuit board controls the heating element to heat the water. When the water temperature returns to the water outlet temperature preset by the user, the control circuit board controls the heating element to stop heating.

[0070] If the user also sets the water output through the control panel, the water flow sensor detects the amount of water flowing through the third water pipe 53 of the water outlet pipe. When the water amount reaches the water output set by the user, the control circuit board controls the corresponding components of the electric kettle to stop pumping water and discharging water.

[0071] Therefore, for a water cooling device of the present application, the water to be cooled is introduced into the cooler main body 13, and the cold air blown out by the cooling fan 11 is sent to the cooler main body 13 through the three-way air guiding assembly 12, so that the temperature of the water flowing through the cooler main body 13 is reduced. At the same time, the three-way air guiding assembly 12 sends the cold air blown out by the cooling fan 11 to the outer wall of the kettle 60, so that the water temperature is accelerated to drop, and the hot water in the electric kettle can be quickly cooled with high cooling efficiency.

This specification is intended to cover any variations, uses, or adaptations of the specification, which follow the general principles of the specification and include common general knowledge or conventional technical means in the technical field not claimed in this specification.
