Description

Technical Field

[0001] This utility model relates to an electric furnace with gravity control function. Background Technology

[0002] Chinese patent document CN219374412U discloses a gravity-controlled household appliance base, including a base shell, a panel assembly, a gravity sensor, and a control board. The panel assembly includes a weighing panel and a supporting panel frame. The supporting panel frame is fixed to the top of the base shell, and the weighing panel and the supporting panel frame are vertically movably connected. The gravity sensor has a first fixed end, a second fixed end, and a sensing end disposed between the two. The first fixed end is fixedly connected to the weighing panel, the second fixed end is fixedly connected to the supporting panel frame, and the sensing end is electrically connected to the control board. During use, when the weight pressing on the base changes in real time, the control board can automatically control the operation of the household appliance. Users can also tap the household appliance to cause a brief change in the weight pressing on the base, after which the control board can control the operation of the household appliance according to a preset weight change logic.

[0003] This technical solution, which controls the switching of its working state through weight changes, is very popular with consumers. However, when this technical solution is directly applied to an electric furnace, the heat generated by the furnace during operation is easily transferred directly to the weighing sensor. The data detected by the weighing sensor when it is overheated is prone to large deviations, which in turn affects the normal operation of the furnace. Therefore, further improvements are needed.

[0037] First Embodiment

[0038] like Figures 1-4 As shown, this electric furnace with gravity control function includes: The main body 1 is divided into a central cavity 11 located in the middle and an electrical cavity 12 located on the outer periphery. The top of the central cavity 11 is provided with an air outlet 111 communicating with the outside, and the bottom of the electrical cavity 12 is provided with an air inlet 121 communicating with the outside. The heating assembly includes a panel 21, a heating plate 22, and a frame 23. The heating plate 22 is fixedly installed at the bottom center of the panel 21, and the frame 23 is fixedly installed on the bottom periphery of the panel 21 and surrounds the heating plate 22 with a heat dissipation gap between them. The frame 23 has a heat dissipation outlet 231 at the top and a heat dissipation inlet at the bottom and is equipped with a cooling fan 232. The heating assembly is movably installed on the central cavity 11. The load cell 3 is fixedly installed between the outer bottom of the frame 23 and the inner bottom of the main body 1. The load cell 3 is close to the air inlet 121 and is at a distance from the outer bottom of the frame 23. Its structure makes the load cell 3 close to the air inlet 121 and slightly away from the heating element, which can reduce the heat radiated directly to the load cell 3 when the heating element is working. In addition, when air is introduced through the air inlet 121, the cold air from the outside can blow towards the load cell 3 first. The air inlet 121, heat dissipation inlet, heat dissipation gap 230, heat dissipation outlet 231, and air outlet 111 sequentially constitute the heat dissipation duct of the electric furnace. Specifically, when the cooling fan 232 is working, the heat dissipation duct generates a unidirectional heat dissipation airflow from the air inlet 121 to the air outlet 111. Cold air from the outside is drawn in by the air inlet 121, first blown towards the weighing sensor 3 to dissipate heat, then blown towards the interior of the heating component to dissipate heat, and finally discharged through the air outlet 111. This technical solution can prioritize the heat dissipation of the weighing sensor 3, effectively avoiding the problem of the weighing sensor 3 being overheated, avoiding large deviations in its detection data, and thus avoiding affecting the normal operation of the electric furnace.

[0039] Furthermore, when the weighing sensor 3 is a set, it is placed at the center of the outer bottom of the frame 23; when there are two or more sets of weighing sensors 3, they are placed around the outer bottom of the frame 23. Those skilled in the art will understand that this solution uses two sets of weighing sensors 3, which are placed on both sides of the outer bottom of the frame 23.

[0040] Furthermore, the bottom of the main body 1 is provided with an installation port, and the installation port is covered with a bottom cover 10. This structure facilitates the assembly of the entire circuit. The air inlet 121 is distributed on the bottom cover 10, realizing the effect of bottom air intake and top air exhaust of the heat dissipation duct, and more effectively avoiding cold and heat turbulence. The weighing sensor 3 is fixedly installed between the outer bottom of the frame 23 and the inner bottom of the bottom cover 10.

[0041] Furthermore, the weighing sensor 3 is sheet-shaped, including a first connecting end 31 located at its center, a second connecting end 32 located at its periphery, and a gravity sensing element disposed between the two; the electric furnace also includes a sensor bracket 4, the sensor bracket 4 having a cover groove 41, the cover groove 41 being fixedly installed on the inner bottom of the bottom cover 10 and pressing the second connecting end 32 tightly against the inner bottom of the bottom cover 10, the cover groove 41 having an opening 411 corresponding to the first connecting end 31, the outer bottom of the frame 23 having a first fixing post 233 extending downward into the opening 411 and fixedly installed with the first connecting end 31, the inner bottom of the bottom cover 10 having a weighing cavity 100 corresponding to the position of the first connecting end 31, the cavity being able to provide space for the deformation displacement of the weighing sensor 3 to ensure the required weight measurement data, as will be understood by those skilled in the art.

[0042] Furthermore, the air outlet 111 is inclined downward from the periphery to the center of the main body 1, and the central cavity 11 is provided with a water receiving tank 131 connected to the inner side of the air outlet 111. When the heating appliance on the electric furnace has an overflow accident, the overflowing liquid can flow into the water receiving tank 131.

[0043] Furthermore, the water receiving tank 131 is provided with a drainage tank 13. The first end of the drainage tank 13 is connected to the water receiving tank 131, and the tail end of the drainage tank 13 penetrates the bottom of the main body 1 to connect to the outside of the electric furnace. Alternatively, the tail end of the drainage tank 13 is connected to the air inlet 121 and connects to the outside of the electric furnace through the air inlet 121. In this embodiment, the latter technical solution is preferred. The drainage tank 13 can discharge the liquid collected in the water receiving tank 131 to the outside of the electric furnace, which will be understood by those skilled in the art.
