Description

Technical Field

[0001] This utility model relates to the field of electric kettle technology, and in particular to an electric kettle that can cool down quickly. Background Technology

[0002] Chinese patent document CN208925887U, published on June 4, 2019, discloses a formula maker, comprising a pot body and a base. The pot body is equipped with an electric heating device and is detachably mounted on the base. The bottom of the pot body is connected to the base via a connector to electrically connect the electric heating device to the base's circuitry. The upper part of the base has a base groove that fits the bottom of the pot body, including a bottom wall and a baffle surrounding the bottom wall. The base has a drainage channel connecting the base groove to the outside of the base. However, the pot body of this formula maker is not entirely glass; it has a metal base plate at the bottom, making its use less hygienic and environmentally friendly. Furthermore, some formula makers on the market use entirely glass pot bodies, which, when filled with hot water, can easily scald the table if placed on a cool surface, and may also cause the pot to crack. The bottom of the glass kettle can be either perfectly flat or not perfectly flat. When the bottom is perfectly flat, there is almost no gap between the kettle and the table when placed on it. Due to atmospheric pressure, the kettle is difficult to lift off the table. When the bottom is not perfectly flat, there is a gap between the kettle and the table. If the kettle is filled with hot water, the air in the gap expands due to thermal expansion and contraction. When the hot water cools down, the air in the gap contracts due to thermal expansion and contraction. At this point, the air pressure in the gap is less than atmospheric pressure, making it difficult to lift the kettle off the table. Furthermore, if there are residues on the bottom of the kettle when it is not perfectly flat, these residues will fill the gap between the kettle and the table, effectively making the gap almost nonexistent. Again, due to atmospheric pressure, the kettle is difficult to lift off the table.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an electric kettle that is simple in structure, hygienic and environmentally friendly, stable and reliable, with a good user experience and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] An electric kettle designed for this purpose that can quickly cool down includes a main unit and a heating kettle. The main unit includes a base and a heating plate mounted on the base.

[0015] The base is equipped with a circuit board, which is electrically connected to the heating plate, the fan, and the first temperature sensor and / or the second temperature sensor. The first temperature sensor and / or the second temperature sensor feed back the detected water temperature to the circuit board, and the circuit board adjusts the fan speed according to the detected water temperature.

[0016] The inner side of the base is provided with a detection device for cooperating with the glass pot. The detection device includes a fixed seat and a rotating seat. The fixed seat is fixed on the base, and the rotating seat is rotatably mounted on the fixed seat. An elastic element is provided between the fixed seat and the rotating seat.

[0017] When the glass pot is installed on the base, it acts on the rotating seat, causing the rotating seat to rotate inward and compress the elastic element;

[0018] When the glass pitcher is removed from the base, the rotating seat rotates outward and resets under the elastic force of the elastic element;

[0019] The rotating base is equipped with a temperature sensing component and a water level detection device. The temperature sensing component includes a heat-conducting cover and a second temperature sensor. The heat-conducting cover is in contact with the glass pot and is located on the front side of the rotating base. The water level detection device is located on the rear side of the rotating base.

[0020] The glass pitcher has a flip-open lid on top, and a lamp assembly for illuminating the liquid inside the pitcher is installed on the lid. The lamp assembly includes a lamp module, a seal, and a heat-insulating and light-transmitting component. The lid has a mounting groove, and the seal is installed in the mounting groove. The heat-insulating and light-transmitting component is installed in the seal. Buckles are provided on both sides of the mounting groove. The lamp module is fixed to the lid by the buckles. The light emitted by the lamp module is transmitted to the liquid inside the glass pitcher through the heat-insulating and light-transmitting component.

[0021] It also includes a power supply device. A handle is provided on one side of the heat sink. The power supply device includes a first magnetic coupler, a second magnetic coupler, a third magnetic coupler, and a fourth magnetic coupler.

A second positioning part is provided at the bottom of the handle. The second positioning part is inserted into the positioning notch so that the handle is fixed on the kettle.

[0024] This electric kettle is made entirely of glass, which is hygienic and environmentally friendly. A heat dissipation cylinder surrounds the glass kettle, with a support surface at its bottom. A gap exists between the bottom of the glass kettle and the support surface, allowing the kettle to suspend itself within the heat dissipation cylinder. When placed on a table, the kettle is supported by the support surface, keeping it suspended above the table and preventing it from touching the surface. This prevents scalding the table with hot water and also prevents the kettle from shattering. Furthermore, because the kettle remains suspended above the table, there is always a gap between the bottom of the kettle and the table surface. The air pressure in this gap is equal to atmospheric pressure, thus eliminating the problem of the kettle being difficult to lift after being placed on the table.

[0025] Moreover, when the kettle is assembled with the main unit, the kettle is supported on the base by the support surface, the heating plate is inserted into the heat dissipation cylinder, and the heating plate is in contact with the bottom of the glass kettle. This structure can eliminate the coupler on the traditional heating plate, thereby reducing the vertical space occupied, which can reduce the height of the electric kettle and thus reduce the overall volume of the electric kettle.

[0026] In addition, a channel is formed between the heat dissipation cylinder and the glass pot to insulate and cool the glass pot. The channel dissipates heat from all directions to the outer wall of the glass pot, thereby achieving rapid cooling of the water to the drinking temperature required by the user.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] See Figures 1-11 The electric kettle that can quickly cool down includes a main unit and a heating pot. The main unit includes a base 1 and a heating plate 3 mounted on the base 1. The heating pot includes a glass pot 2 integrally formed and forming a cavity and a heat dissipation cylinder 4 sleeved around the glass pot 2. The bottom of the heat dissipation cylinder 4 is provided with a support surface 15. There is a gap a between the bottom of the glass pot 2 and the support surface 15 so that the glass pot 2 is suspended in the heat dissipation cylinder 4.

[0040] When the heating pot is assembled with the main unit, the heating pot is supported on the base 1 by the support surface 15, the heating plate 3 is inserted into the heat dissipation cylinder 4, and the heating plate 3 is in contact with the bottom of the glass pot 2, so that the heating plate 3 can heat the water inside the glass pot 2.

[0041] When the heating kettle is separated from the main unit, the heating kettle is supported on the support b by the support surface 15, so that the glass kettle 2 is suspended above the support b, such as a table. When the heating kettle is placed on the table, the heating kettle is supported on the table by the support surface 15, and the glass kettle 2 does not contact the table, so as to prevent the table from being scalded after the glass kettle is filled with hot water, and also to prevent the glass kettle from shattering.

[0042] A channel 5 is formed between the heat dissipation cylinder 4 and the glass pot 2 for heat insulation and cooling of the glass pot 2. The lower end of the channel 5 forms an air inlet 41 and the upper end forms an air outlet 14 that connects to the outside. The bottom of the heat dissipation cylinder 4 is provided with an open support opening 42, which extends downward beyond the bottom of the glass pot 2. The heating plate 3 passes through the support opening 42 and enters the heat dissipation cylinder 4. The heat dissipation cylinder 4 also serves as heat insulation to prevent users from touching the glass pot 2 and burning their hands.

[0043] The base 1 is equipped with a fan 9 and an air duct cavity 10. The air inlet of the fan 9 is connected to the outside, and the air outlet of the fan 9 is connected to the air duct cavity 10. The air duct cavity 10 is connected to the air inlet 41 through the support opening 42, and the air outlet 14 is located at the top of the heat sink 4.

[0044] An electrical cavity 35 is provided inside the base 1, and a fan 9 is located inside the electrical cavity 35 and at the bottom of the base 1. An air inlet 36 is provided at the bottom of the base 1 to connect to the outside, and the air inlet end of the fan 9 is connected to the air inlet 36.

[0045] The heating pot includes a mounting ring 8, which is located on the top of the heat dissipation cylinder 4 and between the heat dissipation cylinder 4 (outer shell 6) and the glass pot 2. The glass pot 2 is fixed inside the heat dissipation cylinder 4 by the mounting ring 8. The mounting ring 8 is a rubber part and is press-fitted with the heat dissipation cylinder 4 (outer shell 6) and the glass pot 2 respectively, thereby fixing the glass pot 2 inside the heat dissipation cylinder 4. The inner side of the mounting ring 8 is provided with a protrusion 33, and the outer side of the glass pot 2 is provided with a recess 34. The protrusion 33 is inserted into the recess 34.

[0046] The heat sink 4 includes an outer shell 6 and a support base 7. The bottom of the outer shell 6 is connected to the support base 7 by screws. The bottom of the support base 7 extends beyond the bottom of the glass pot 2 and is supported on the base 1 or the support b.

[0047] Channel 5 includes a first channel 11 and a second channel 12 arranged vertically. The first channel 11 is formed between the outer shell 6 and the glass pot 2, and the second channel 12 is formed between the support base 7 and the glass pot 2. The bottom of the outer shell 6 has a series of through holes 13 arranged in a ring. Air outlets 14 connect to the outside and are arranged in a ring on the mounting ring 8. The air inlet 41, the second channel 12, the through holes 13, the first channel 11, and the air outlet 14 are sequentially connected. Figure 1 As indicated by the arrow, when the fan 9 is working, outside air enters the air duct cavity 10 through the air inlet 36, and then enters the second channel 12 and the first channel 11 in sequence to dissipate heat from the outer wall of the glass pot 2, thereby cooling the water inside the glass pot 2. Finally, the air is discharged to the outside through the air outlet 14.

[0048] The support surface 15 is set at the bottom of the support base 7. When the heating kettle is assembled with the main unit, the bottom of the support base 7 is inserted into the groove 56 of the base 1. The bottom of the groove 56 is provided with a support surface 16. The support base 7 is supported on the support surface 16 through the support surface 15. The gap a = 3~5mm. By designing a reasonable gap a, the glass kettle 2 is suspended in the heat dissipation cylinder 4 without occupying too much vertical space. If the gap is set too small, the bottom of the glass kettle 2 may touch the table. If the gap is set too large, the center of gravity of the heating kettle will be too high, occupying a lot of space, with poor installation stability, and it will not be aesthetically pleasing.

[0049] The heating plate 3 is provided with a first temperature sensor 17 for detecting the water temperature inside the glass kettle 2, and the first temperature sensor 17 is located at the bottom of the glass kettle 2; and / or, the base 1 is provided with a second temperature sensor for detecting the water temperature inside the glass kettle 2, and the second temperature sensor is located on the side of the glass kettle 2; the operation of the heating plate 3 is controlled by detecting the water temperature inside the glass kettle 2 through the temperature sensor.

[0050] A circuit board 32 is provided on the base 1. The circuit board 32 is electrically connected to the heating plate 3, the fan 9, and the first temperature sensor 17 and / or the second temperature sensor. The first temperature sensor 17 and / or the second temperature sensor feeds back the detected water temperature to the circuit board 32. The circuit board 32 adjusts the speed of the fan 9 according to the detected water temperature. That is, when the water temperature in the glass kettle 2 is high, the fan speed is increased, and when the water temperature in the glass kettle 2 is low, the fan speed is reduced to balance energy consumption, noise and cooling speed, so that the electric kettle is more energy-efficient and quieter.

[0051] The first temperature sensor 17 is sealed and fixed between the heating plate 3 and the glass pot 2 by a sealing component 37. The sealing component 37 is a silicone ring, which is pressed between the heating plate 3, the glass pot 2 and the base 1.

[0052] The inner side of the base 1 is provided with a detection device for cooperating with the glass pot 2. The detection device includes a fixed seat 18 and a rotating seat 19. The fixed seat 18 is fixed on the base 1, and the rotating seat 19 is rotatably mounted on the fixed seat 18. An elastic element 20 is provided between the fixed seat 18 and the rotating seat 19. The elastic element 20 is a spring.

[0053] When the glass pot 2 is installed on the base 1, it acts on the rotating seat 19 to make the rotating seat 19 rotate inward and compress the elastic element 20;

[0054] When the glass pot 2 is removed from the base 1, the rotating seat 19 rotates outward and resets under the elastic force of the elastic element 20;

[0055] A temperature sensing component and a water level detection device 43 are provided on the rotating base 19. The temperature sensing component includes a heat-conducting cover 44 and a second temperature sensor (not shown in the figure). The heat-conducting cover 44 is in contact with the glass pot 2. The heat-conducting cover 44 is located on the front side of the rotating base 19, and the water level detection device 43 is located on the rear side of the rotating base 19, that is, the heat-conducting cover 44 is located in front of the water level detection device 43. When the glass pot 2 is installed on the base 1, the temperature sensing component and the water level detection device 43 can detect the temperature or water level of the water in the glass pot 2.

[0056] In this embodiment, the first temperature sensor 17 and the second temperature sensor are set simultaneously, and the water level detection device 43 is a water level probe, thereby realizing the temperature detection and water level detection of the water in the glass pot 2.

[0057] Water level probe detection principle: When the water level in the glass kettle 2 changes, the capacitance of the water level detection device 43 will change. The change in capacitance is directly fed back to the circuit board 32, thereby realizing the water level detection function. The circuit board 32 can determine whether the water level in the glass kettle 2 is too low by comparing it with the preset data, thereby achieving the effect of preventing dry burning.

[0058] A rotating shaft 38 is provided on the rotating seat 19, and a rotating hole 39 is provided on the fixed seat 18. The rotating shaft 38 is rotatably connected to the rotating hole 39.

[0059] A notch 55 is provided on one side of the support base 7, and one end of the rotating base 19 extends into the heat dissipation cylinder 4 through the notch 55. The heat conduction cover 44 is provided at one end of the rotating base 19.

[0060] The glass container 2 has a flip-open lid 21 on its top. The lid 21 is equipped with a lamp assembly for illuminating the liquid inside the glass container 2. The lamp assembly includes a lamp module 22, a sealing element 23, and a heat-insulating and light-transmitting element 24. The lid 21 has a mounting groove 25. The sealing element 23 is installed in the mounting groove 25, and the heat-insulating and light-transmitting element 24 is installed in the sealing element 23. The mounting groove 25 has buckles 26 on both sides. The lamp module 22 is fixed to the lid 21 by the buckles 26. The light emitted by the lamp module 22 is transmitted to the liquid inside the glass container 2 through the heat-insulating and light-transmitting element 24. The lid 21 also has an opening 40. The lamp module 22 is pressed against the end face of the sealing element 23 by the buckles 26, so that the sealing element 23 is fixed in the opening 40, thus achieving a sealed connection.

[0061] The sealing element 23 ensures good sealing and heat insulation, preventing liquid in the glass container 2 from entering the lamp module 22. At the same time, the heat-insulating and light-transmitting element 24 effectively blocks the water temperature or water vapor in the glass container 2 from affecting the lamp module 22, protecting the lamp module 22 from damage. It can also effectively transmit the light emitted by the lamp module 22, so that the liquid inside the glass container 2 can be fully illuminated.

[0062] The lamp module 22 is a lighting lamp or an ultraviolet lamp. The lighting lamp is used to illuminate the internal environment of the glass pot 2 and can also be used as an ambient light. The ultraviolet lamp is used to sterilize the inside of the glass pot 2 to ensure the hygiene of the inside of the glass pot 2.

[0063] When the lamp module 22 is a lighting lamp, the outer shell 6 is transparent, allowing the user to see the internal environment of the glass kettle 2. When the lamp module 22 is a UV lamp, the outer shell 6 is opaque, which can prevent the ultraviolet rays emitted by the UV lamp from shining on the outside of the electric kettle and causing harm to people. Therefore, the outer shell 6 and the support base 7 are two separate parts, which are for replacing the transparent or opaque outer shell.

[0064] It also includes a power supply device. A handle 51 is provided on one side of the heat sink 4. The power supply device includes a first magnetic coupler 27, a second magnetic coupler 28, a third magnetic coupler 29, and a fourth magnetic coupler 30. The first magnetic coupler 27 is provided on the cover 21, the second magnetic coupler 28 is provided on the top of the handle 51, the third magnetic coupler 29 is provided on the bottom of the handle 51, and the fourth magnetic coupler 30 is provided on the base 1.

The second magnetic coupler 28 is electrically connected to the third magnetic coupler 29. The third magnetic coupler 29 and the fourth magnetic coupler 30 are coupled to each other. A circuit board 32 is provided on the base 1. The circuit board 32 is electrically connected to the fourth magnetic coupler 30, thereby realizing the power supply to the lamp module 22.

[0065] When the heating kettle is installed on the base 1, the third magnetic coupler 29 and the fourth magnetic coupler 30 are coupled to each other. When the cover 21 is closed, the first magnetic coupler 27 and the second magnetic coupler 28 are coupled to each other, so that the power supply device can automatically establish a reliable electrical connection, simplifying the user's operation, while ensuring the stability of the power supply and avoiding power interruption or lamp component failure due to poor contact.

[0066] The first magnetic coupler 27, the second magnetic coupler 28, the third magnetic coupler 29, and the fourth magnetic coupler 30 are magnetic connectors. They use the magnetic attraction force to attract the two parts of the connector together, thereby achieving an electrical connection.

[0067] The handle 51 has a wire-threading cavity 52. ​​The power line connecting the second magnetic coupler 28 and the third magnetic coupler 29 is arranged in the wire-threading cavity 52 for easy wiring.

[0068] The handle 51 has a connecting buckle 45 at the top, and the glass kettle 2 has a snap-fit ​​edge 46 at the top. The connecting buckle 45 and the snap-fit ​​edge 46 are snapped together. The handle 51 has a first positioning part 47 at the top, and the outer shell 6 has a first positioning surface 48 at the top. The first positioning part 47 rests downward against the first positioning surface 48. The support base 7 has a positioning notch 49 on one side. The handle 51 has a second positioning part 50 at the bottom. The second positioning part 50 is inserted into the positioning notch 49 to fix the handle 51 on the kettle. The heat dissipation cylinder 4 is composed of two separate outer shells 6 and a support base 7 to facilitate the assembly of the handle 51 on the kettle and prevent the handle 51 from getting stuck during installation.

[0069] The top of the mounting ring 8 is provided with a second positioning surface 53, the first positioning part 47 abuts downward against the second positioning surface 53, and a sealing element 54 is provided between the connecting buckle 45 and the buckle edge 46.

[0070] The top of the air duct cavity 10 is open, and the glass pot 2 is located above the air duct cavity 10. The bottom of the air duct cavity 10 is provided with a drain hole 31. If water leaks out of the glass pot 2, the water will flow to the bottom of the air duct cavity 10 and then be discharged out of the electric kettle through the drain hole 31.
