Detailed Description of the Preferred Embodiments

[0030] In order to more clearly understand the specific technical solutions, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0031] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0032] Embodiment 1

[0033] As Figure 1 and Figure 2 As shown, a gravity-sensing heating device 100 disclosed in the present application includes a box body 20 and a lower coupler 10 disposed on the box body 20. A main control board (not shown) for controlling heating is disposed inside the lower coupler 10. A gravity tray 30 for carrying an external heating appliance and a gravity-sensing module 21 for sensing the mass of the heating appliance are further disposed on the box body 20. The gravity-sensing module 21 is electrically connected to the main control board, and the gravity-sensing module 21 is connected to the gravity tray 30. When the heating appliance is placed on the gravity tray 30, the gravity-sensing module 21 senses the first mass information of the current heating appliance and sends the first mass information to the main control board. The main control board calculates the third mass information of the liquid in the current heating appliance based on the first mass information and the pre-stored second mass information of the heating appliance, and the main control board controls the heating appliance to heat the liquid according to the third mass information. When the liquid is heated to a preset temperature, the main control board controls the heating appliance to stop heating or reduce heating.

[0034] In the above embodiment, the gravity-sensing heating device disclosed in the present application includes a main control board and a gravity-sensing module 21 that can sense the mass information of the liquid in the heating appliance, making the sensed mass information of the liquid to be heated more accurate. And the main control board can output a corresponding current to the heating appliance according to the mass information of the liquid to control the heating appliance to heat the liquid, making the heating appliance heat the liquid more accurately. In addition, the heating appliance is placed on the gravity tray 30, which can effectively prevent heat from being dissipated to the main control board, and the main control board is disposed inside the lower coupler 10, which can protect the main control board and make the main control board not easily burned out.

[0035] Among them, the lower coupler 10 is coupled (or plugged) to the upper coupler 71 of the heating appliance, and the main control board is arranged at the lower end of the lower coupler 10. The lower coupler 10 is arranged on the gravity tray 30. The gravity tray 30 is preferably a heat-resistant hard plastic plate. When the gravity induction heating device 100 is powered on and the heating appliance is placed on the gravity tray 30, after three to five seconds, the gravity induction module 21 senses the total mass of the heating appliance and records it as the first mass information. The gravity induction module 21 sends the first mass information to the main control board. The main control board subtracts the mass of the heating appliance itself, that is, the pre-stored second mass information of the heating appliance, from the first mass information to obtain the mass of the liquid in the heating appliance, which is the third mass information, commonly known as "tare weight", and can accurately obtain the mass of the liquid in the heating appliance. The main control board controls the heating appliance to heat the liquid to a preset temperature according to the third mass information, such as 100 degrees, 99 degrees, 95 degrees, 50 degrees, etc. When the preset temperature is reached, the main control board controls the heating appliance to stop or reduce the heating of the liquid. The preset temperature can be a temperature value pre-stored in the main control board, or in the third embodiment, the preset temperature can be input into the main control board through the control button 411 on the control board 41. The temperature value of the liquid in the heating appliance can be obtained by the main control board through a temperature sensor for measuring the temperature of the heating appliance.

[0036] It is further worth noting that the second mass information can be pre-stored in the main control board by directly inputting it into the main control board. For example, in the third embodiment, through the control button 411 on the control board 41, the second mass information is input into the main control board. It can also mark a certain mass information obtained by the gravity induction module 21 as the second mass information through the control button 411. For example, when the gravity induction heating device 100 is powered on and the heating appliance is placed on the gravity tray 30, within three seconds, manually mark the mass detected by the current gravity tray 30 as the second mass information through the control button 411.

[0037] For the gravity induction heating device of this embodiment, the main control board can obtain the initial temperature value of the heating appliance through the temperature sensor. The preset temperature minus the initial temperature value is the Celsius temperature difference; and obtain the third mass information of the liquid in the heating appliance through the gravity induction module, and calculate the required heating power. After reaching the required heating power, the main control board controls the heating appliance to stop heating or reduce heating to prevent the heating appliance from dry burning.

[0038] In addition, for the gravity induction heating device of this embodiment, the main control board can continuously obtain the third mass information through the gravity induction module. When the third mass information is lower than the first threshold, the main control board controls the heating appliance not to heat to prevent the heating appliance from dry burning.

[0039] Embodiment 2

[0040] In a preferred embodiment, as Figure 2 and Figure 7 shown, the gravity induction heating device 100 further includes a balance plate 50 for balancing the gravity tray 30. The gravity tray 30 is disposed above the balance plate 50. L-shaped plates 51 are disposed at both ends of the balance plate 50. The balance plate 50 is integrally connected to the gravity induction module 21 through the L-shaped plates 51. Preferably, as Figure 6 shown, the box body 20 includes a support plate 60 for mounting the lower coupler 10 and the gravity tray 30. A column 33 is disposed at the lower end of the gravity tray 30. The column 33 passes through the support plate 60 and abuts against the balance plate 50. Preferably, the support plate 60 includes a support frame 61 and mounting seats 63 disposed at both ends of the support frame 61. The gravity induction module 21 is fixed on the mounting seats 63. The balance plate 50 is disposed within the support frame 61.

[0041] In the above embodiment, both the balance plate 50 and the gravity tray 30 are circular, and their centers of gravity coincide. The body of the gravity tray 30 is disposed parallel to the balance plate 50, so that the heat on the gravity tray 30 is not easily dissipated downward to the balance plate 50 to interfere with the main control board and the gravity induction module 21. The L-shaped plates 51 and the gravity induction module 21 are integrally and firmly connected by anti-loosening screws, so that the weight on the gravity tray 30 can be accurately transmitted to the gravity induction module 21 through the balance plate 50. Among them, in order to make the balance plate 50 more balanced, two or four gravity induction modules 21 can be provided and evenly disposed around the balance plate 50. The support frame 61 is conducive to the installation and positioning of the balance plate 50, and the mounting seats 63 are conducive to the installation of the gravity induction module 21.

[0042] Embodiment Three

[0043] In a preferred embodiment, as Figures 3 - 6 shown, the box body 20 further includes a panel 40 disposed on the support plate 60. The gravity tray 30 is disposed above the panel 40. The gravity tray 30 includes a separation ring 31. The separation ring 31 sequentially passes through the panel 40 and the support plate 60. The lower coupler 10 is disposed within the separation ring 31. Preferably, a control board 41 is disposed on the panel 40. The control board 41 is electrically connected to the main control board. Control buttons are disposed on the control board 41. Preferably, drain holes 62 and holes are further disposed on the support plate 60. The drain holes 62 are vertically connected to the panel 40. The drain holes 62 are disposed outside the separation ring 31.

[0044] In the above-described embodiment, the panel 40 may be a waterproof panel, and a display screen may also be provided on the panel 40. A gap 32 is provided between the gravity tray 30 and the panel 40, which can prevent the heat on the gravity tray 30 from being transferred to the panel 40 and burning out the control board 41. The control buttons 411 on the control board 41 facilitate the user to control the main control board. Specifically, the control buttons 411 can be used to input preset temperature values, first thresholds, second quality information, etc. as described in Embodiment 3.

[0045] The isolation ring 31 can prevent heat and liquid from entering the main control board, thereby protecting the main control board at the lower end of the lower coupler 10. The drain hole 62 can drain the liquid splashed by the heating appliance on the panel 40, thus avoiding a short circuit of the circuit. The lower coupler 10 is installed in the hole through the gravity tray 30.

[0046] It is further worth noting that in this embodiment, the lower coupler 10 is installed within the isolation ring 31 of the gravity tray 30. The isolation ring 31 sequentially passes through the holes of the panel 40 and the support plate 60, and the upright post 33 of the gravity tray 30 also sequentially passes through the panel 40 and the support plate 60 and abuts against the balance plate 50, thereby conducting the weight of the gravity tray 30 to the balance plate 50.

[0047] Embodiment 4

[0048] In a preferred embodiment, as Figures 7 - 9 shown, preferably, the lower coupler 10 includes a socket 11 that mates with the upper coupler 71 of the heating appliance. The socket 11 includes a socket hole 111 for plugging in the upper coupler 71 and a support column 12. The center lines of the support column 12, the gravity tray 30, and the socket 11 coincide. The gravity induction heating device 100 further includes a temperature sensor and a water adding member for adding water to the heating appliance. The water adding member and the temperature sensor are both provided on the box body, and the water adding member and the temperature sensor are both electrically connected to the main control board. Preferably, the main control board is a main control MCU that can output a corresponding current I according to the quality information, where I = KM / R, K is a coefficient, M is the mass of the liquid, and R is the resistance of the heating appliance for heating.

[0049] In the above-described embodiment, when the third quality information is greater than the second threshold, the main control board controls the water adding member to stop adding water to prevent the liquid in the heating appliance from overflowing and burning out the gravity induction heating device. The second threshold can be preset in the main control board or input into the main control board through the control button 411. In addition, when the third quality information is less than the first threshold, the main control board controls the water adding member to add water to the heating appliance to prevent the heating appliance from dry burning and burning out due to lack of water.

[0050] The socket hole 111 on the socket 11 facilitates the insertion of the upper coupler 71 of a heating appliance (such as a kettle 70), and the support post 12 facilitates the support of the upper coupler 71. The coincidence of the center lines of the support post 12, the gravity tray 30, and the socket 11 can make the centers of gravity coincide, enabling the lower coupler 10 to more stably connect to the upper coupler 71. The water filling member can be connected to automatic water or barreled water to automatically fill the kettle 70 with water. The temperature sensor is provided on the lower end cover 22 and can transmit the temperature information of the liquid to the main control MCU. As Figure 8 shown, the main control MCU can not only control the water filling of the water filler but also input a suitable current to the heating appliance by adjusting the resistance value, enabling the heating appliance to accurately heat water or keep the water warm. When the kettle 70 is boiling water, the current output by the main control board can be calculated by the formula I = KM / R. When the kettle 70 is keeping warm or turned off, the main control board reduces the output current or directly shuts down. It can be understood that the gravity induction heating device 100 of the present invention can be applied to an electric kettle or an electric ceramic stove.

[0051] In summary, the gravity induction heating device 100 disclosed in the present application uses the gravity tray 30 to carry the heating appliance, and then controls the heating appliance to heat through the main control board, enabling the heating appliance to accurately heat the liquid. The gravity tray 30 and the lower coupler 10 can also protect the main control board, thereby increasing the service life.
