Description

Technical Field

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

[0002] Electric kettles are common household appliances in every family. Traditional electric kettles only have the single function of boiling water. If the boiled water is to reach a suitable drinking temperature, it can only be allowed to cool naturally, which requires a long wait. If the lid is opened to dissipate heat, 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 cooling function have appeared on the market. For example, the Chinese utility model patent with announcement number CN209898978U discloses a fast-cooling healthy water kettle, comprising a kettle body, a kettle lid, a water cooling mechanism, a heat dissipation fan, and a bracket. The kettle lid is arranged at the top of the kettle body, a water outlet is provided at the bottom of the kettle lid shell, and a water pump is arranged inside the kettle lid, the water suction port of the water pump is connected to a water suction pipe, and the bottom end of the water suction pipe is located at the bottom of the kettle body; the water outlet of the water pump is connected to a first water supply pipe and a second water supply pipe, the other end of the first water supply pipe is connected to the water outlet, and the other end of the second water supply pipe extends out of the kettle lid, and switches for controlling the water on and off of the first water supply pipe and the second water supply pipe are respectively provided on the kettle lid shell; a bracket is provided on the outside of the kettle body, a heat dissipation fan is fixedly connected to the outer end surface of the bracket, the water cooling mechanism is installed on the heat dissipation fan shell, the water inlet end of the water cooling mechanism is connected to the outer end of the second water supply pipe, the water outlet end of the water cooling mechanism is connected to a return pipe, the other end of the return pipe extends into the kettle lid and is connected with the water outlet.

[0004] However, the applicant has found through research that the above-mentioned fast cooling health kettle mainly uses the heat dissipation block in the water cooling mechanism to cool the hot water, and further dissipates the heat through the heat dissipation fan. This method of cooling is slow and the cooling effect needs to be further improved. Utility Model Content

Figure 7 This is a schematic diagram of water flow when a user takes water from an electric kettle of the present application.

[0046] As shown in the figure, in order to solve the technical problems of slow cooling speed and poor cooling effect of kettles in the prior art, the present application provides a water temperature regulating device for an electric kettle with a kettle, which includes a water inlet pipe, a water pump 40, a water outlet pipe and a semiconductor refrigerator 10.

[0047] Specifically, the water inlet pipe is connected to the kettle, the water pump 40 is connected to the water inlet pipe, and the water outlet pipe is connected to the water pump 40, so as to pump water from the kettle into the semiconductor refrigerator 10, or pump water from the kettle into other components of the electric kettle. Furthermore, the semiconductor refrigerator 10 has a cooling flow channel for water circulation. The semiconductor refrigerator 10 is connected to the water outlet pipe, and the water pump 40 is used to pump water from the kettle into the semiconductor refrigerator 10, supplying water to the cooling flow channel of the semiconductor refrigerator 10.

[0048] In one 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 having two inlet ports and one outlet port. The first branch pipe 21 is connected to the kettle, the second branch pipe 22 is connected to the outlet port of the first three-way solenoid valve 31, and the second branch pipe 22 is connected to the water pump 40. The first branch pipe 21 and the third branch pipe 23 are respectively connected to the two inlet ports of the first three-way solenoid valve 31. Specifically, when the water in the kettle needs to be cooled, the water is drawn from the kettle through the first branch pipe 21, enters the first three-way solenoid valve 31, and then flows into the second branch pipe 22. The water is then pumped into the semiconductor refrigerator 10 by the water pump 40 for cooling.

[0049] Preferably, the third branch pipe 23 is an air inlet pipe for draining residual water from the pipes of the water temperature control device. Specifically, when draining the pipes, the inlet of the first three-way valve connected to the first branch pipe 21 is closed, while the inlet connected to the third branch pipe 23 is opened. Air flows from the third branch pipe 23 through the first three-way solenoid valve 31 into the second branch pipe 22, then passes through the water pump 40 and the outlet pipe, squeezing the water out of the pipes.

[0050] 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 first water pipe 51 is connected to the water pump 40. The second three-way solenoid valve 32 is a three-way solenoid valve having one water inlet and two water outlets. The water inlet of the second three-way solenoid valve 32 is connected to the first water pipe 51. The second water pipe 52 is connected to the semiconductor refrigerator 10. The second water pipe 52 and the third water pipe 53 are respectively connected to the two water outlets of the second three-way solenoid valve 32. Specifically, the second water pipe 52 is connected to the kettle and is used to transport water cooled by the semiconductor refrigerator 10 to the kettle. This allows the water to be circulated into the semiconductor refrigerator 10 for cooling, improving the cooling efficiency of the water and achieving a better cooling effect. The third water pipe 53 is used to transport the water in the kettle to other locations.

[0051] 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 the electric kettle, the three-way solenoid valve is connected to a control circuit board or other components that can receive input signals, process data, perform logic control, and drive the electric kettle to work, thereby realizing automatic control of the flow direction or flow rate of the fluid.

[0052] In one embodiment, the semiconductor refrigerator 10 includes a cooler 12, a semiconductor cooling sheet 13, a heat conducting plate 14 and a cooling fan 15. The cooler 12 has a cooling channel inside, the semiconductor cooling sheet 13 is attached to the outer surface of the cooler 12, the heat conducting plate 14 is attached to the outer surface of the semiconductor cooling sheet 13, and the cooling fan 15 is arranged on the outside of the cooler 12 and the air suction side is arranged adjacent to the heat conducting plate 14.

[0053] It should be noted that a semiconductor cooler, also known as a thermoelectric cooler or Peltier cooler, is a device that uses the thermoelectric effect of semiconductor materials to achieve cooling. Its operating principle is based on the Seebeck effect and the Peltier effect, two types of thermoelectric effect. The thermoelectric effect refers to the absorption or release of heat when an electric current forms a galvanic couple between different conductors or semiconductor materials. The principle of using a semiconductor cooler to cool water is as follows: the semiconductor cooler is composed of many pairs of alternating N-type and P-type semiconductor materials. N-type semiconductors have excess free electrons, while P-type semiconductors have "holes," which are states where electrons are missing. When current passes through these alternating N-type and P-type materials, electrons flow from the N-type material to the P-type material, simultaneously absorbing or releasing heat at the interface. At the cold end of the cooler, the electrons release energy as they flow from the N-type material to the P-type material, causing the temperature at that end to drop, which is where the cooling effect occurs. At the hot end of the cooler, the electrons absorb energy as they flow from the P-type material to the N-type material, causing the temperature at that end to rise. Therefore, a heat sink is usually required to dissipate this heat. The cold end of the semiconductor refrigeration chip contacts water or other media that need to be cooled, and the temperature of the medium is reduced by absorbing heat. At the same time, the hot end needs to be connected to a radiator or other heat dissipation system to maintain cooling efficiency.

[0054] Preferably, the surface of the semiconductor refrigeration plate 13 is coated with silicone grease (also known as thermal grease or heat dissipation paste). Silicone grease is a heat-conducting material that can fill the tiny gaps between the semiconductor refrigeration plate 13 and the radiator or the object being cooled. Therefore, coating the surface of the semiconductor refrigeration plate 13 with silicone grease can, on the one hand, reduce thermal resistance and improve heat conduction efficiency, thereby improving the cooling effect of the semiconductor refrigerator 10 on water. On the other hand, between the semiconductor refrigeration plate 13 and the heat conducting plate 14, due to the incomplete surface flatness, there will be tiny gaps. These gaps will form thermal resistance and reduce the heat conduction efficiency, while silicone grease can fill these gaps, reduce the contact thermal resistance, and improve the cooling effect of the semiconductor refrigerator 10 on water. In other aspects, since air is a poor conductor of heat, if there is an air layer between the semiconductor refrigeration plate 13 and the heat conducting plate 14, the heat conduction efficiency will be significantly reduced. Silicone grease can exclude air and prevent the formation of an air layer, ensuring good thermal contact between the semiconductor refrigeration plate 13 and the heat conducting plate 14, so that the heat conducting plate 14 can efficiently conduct the heat of the water absorbed by the semiconductor refrigeration plate 13, thereby improving the cooling efficiency and cooling speed of the water and achieving a better cooling effect.

[0055] Preferably, the heat conducting plate 14 is made of aluminum. Aluminum is a good thermal conductor and has better thermal conductivity than many other metal materials. It can effectively transfer heat from the heat source to the heat conducting plate 14, thereby improving the cooling effect of the semiconductor refrigerator 10 on the water.

[0056] Specifically, when the water that needs to be cooled is passed into the cooling channel inside the cooler 12, the cold end of the semiconductor refrigeration plate 13 attached to the outer surface of the cooler 12 absorbs the heat of the water flowing through the cooler 12, and the heat absorbed by the semiconductor refrigeration plate 13 is conducted out through the heat conduction plate 14 attached to the outer surface of the semiconductor refrigeration plate 13, and the heat is dissipated through the cooling fan 15, thereby achieving rapid cooling of the water and a faster cooling speed.

[0057] Preferably, the semiconductor refrigerator 10 further includes a positioning bracket 16 and a fixing pressing plate 11 , which facilitate relative fixation of the cooler 12 , the semiconductor cooling plate 13 , the heat conducting plate 14 and the cooling fan 15 .

[0058] In one embodiment, cooler 12 is made of stainless steel. Because stainless steel is highly effective at regulating temperature, cooler 12 made of stainless steel effectively cools water. Furthermore, stainless steel is water-friendly and resistant to low acid and alkali conditions. Even when used as a long-term water storage container, it does not cause secondary contamination, ensuring clean water quality. Furthermore, coolers made of stainless steel have a long service life.

[0059] The present application also provides an electric kettle, which includes a kettle 60 and the above-mentioned water temperature regulating device, and the water inlet pipe of the water temperature regulating device is connected to the kettle 60.

[0060] In one embodiment, the electric kettle also includes a main body 70. Preferably, the water temperature regulating device is arranged inside the main body 70, and the outer wall of the main body 70 is provided with an air inlet 711 and an air outlet 712, so that the cooling fan 15 can draw in the cold air outside the main body 70 to dissipate the heat of the water temperature regulating device, and dissipate the heat out of the main body 70, thereby increasing the cooling speed of the water by the water temperature regulating device.

[0061] Preferably, the main body 70 has a water outlet port 73 that can be communicated with the third water pipe 53 of the water outlet pipeline, and the water in the electric kettle is transported out through the water outlet port 73 for the user to drink.

[0062] Preferably, the bottom of the main body 70 has a heat dissipation vent 74 .

[0063] In one embodiment, the main body 70 has a control circuit board and a water flow sensor inside. The water flow sensor is installed on the water outlet pipe. The water flow sensor is electrically connected to the control circuit board so that the electric kettle can supply water to the customer in a quantitative manner.

[0064] It should be noted that the control circuit board is a circuit board in the electric kettle used to implement specific control functions. It can be a microcontroller control board or the like that can receive input signals, process data, perform logic control, and drive the electric kettle to work.

[0065] 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, and controlling the operation and output of the equipment. 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 the 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 can also control the outlet and inlet ends of the three-way solenoid valve to close, so as to achieve quantitative water output to the user.

[0066] Specifically, in the present invention, the water flow sensor is connected 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 amount of water flowing through the water outlet pipe. When the water volume reaches the water output volume 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, thereby realizing the function of quantitative and accurate water discharge of the electric kettle.

[0067] 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 to avoid heating the kettle 60 in a water-free state, preventing dry burning and damage, which may lead to dangerous accidents.

[0068] Preferably, the water flow sensor of the present application can also indirectly judge the water level in the kettle 60 by detecting the water flow rate flowing through the water outlet pipe. When the water in the kettle 60 reaches the set water level, the water flow sensor will send a signal to the control circuit to automatically cut off the power to the kettle 60 and stop heating. This ensures that the water will not overflow or boil due to overheating, thereby preventing dangerous accidents.

[0069] In this embodiment, a temperature sensor is 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 .

[0070] Specifically, the user sets the desired outlet water temperature in advance. When the water in the electric kettle boils, the water temperature adjustment device in the electric kettle starts to work and cools the water. When the temperature sensor detects that the water temperature in the kettle 60 has reached the user-set outlet water temperature, the temperature sensor transmits a signal to the control circuit board, which controls the water temperature adjustment device to stop working, thereby achieving the electric kettle's ability to accurately cool the water, allowing the user to set the outlet water temperature of the electric kettle according to their needs.

[0071] Specifically, the temperature sensor can also detect the temperature of the water in the kettle 60. When the water temperature reaches the set heating temperature, the sensor sends a signal to the control circuit board to stop the heating element. By monitoring the water temperature, the temperature sensor can prevent the water in the kettle 60 from boiling over or causing dry boiling due to overheating, thereby protecting the safety of the device and the user.

[0072] Preferably, the temperature sensor can also detect the water temperature and maintain it at a set constant temperature, ensuring that the water maintains a constant temperature within the required time.

[0073] In this embodiment, the main body 70 has a control panel on its exterior, which is electrically connected to the control circuit board. The control panel provides an interface for the user to interact with the electric kettle, displaying information and controlling the kettle. User input is transmitted via the control panel to the control circuit board, which then executes the corresponding control logic. Specifically, the user can use the control panel to control the kettle to start or stop heating water, as well as to control the water output and temperature. Accordingly, the control panel can display relevant information about the electric kettle, such as the water output and the water temperature in the kettle 60.

[0074] 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 outlet via a power cord. When the lower coupler 72 is connected to the power source, when the upper coupler and the lower coupler 72 are connected, the heating element can heat the water in the kettle 60. Preferably, a water inlet pipe runs 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, so that the water in the kettle 60 is pumped into the semiconductor refrigerator 10 for cooling, or the water in the kettle 60 is pumped out for drinking.

[0075] It can be understood that the lower coupler 72 is electrically connected to other components of the electric kettle that need to be powered to work. The lower coupler 72 is connected to the power socket through a power cord to supply power to other components inside the electric kettle that need to be powered to work.

[0076] In a preferred embodiment, the kettle 60 has a kettle lid, which includes a first cover 611 and a second cover 612. 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. The lifting mechanism 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 to move the second cover 612 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 to allow the water vapor in the kettle 60 to be emitted through the opening. This can further improve the cooling efficiency of the water in the kettle 60.

[0077] 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 on the premise that the water has been boiled, on the one hand, the control circuit board controls the water pump 40 to pump water into the semiconductor refrigerator 10 for cooling and then flow back to the kettle 60. 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 controls the water temperature regulating device to continue 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 31 connected to the second branch pipe 22 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 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 set by the user, the control circuit board controls the heating element to stop heating.

[0078] 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.

[0079] Therefore, a water temperature control device of the present application passes the water to be cooled into a cooler 12, and the heat of the water in the cooler 12 is absorbed by a semiconductor refrigeration plate 13. Since the thermal inertia of the semiconductor refrigeration plate 13 is very small, the cooling time is very fast, thereby improving the speed and efficiency of the overall cooling of the water temperature control device. The heat absorbed by the semiconductor refrigeration plate 13 is then further conducted away by a heat conducting plate 14, and this heat is drawn out by a cooling fan 15, so that the semiconductor refrigeration plate 13 can continue to cool, further improving the overall cooling effect of the water temperature control device. The hot water in the electric kettle is quickly cooled, and the cooling efficiency is higher.
