DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0021] Please refer to Figures 1 to 8 , shows an electric heating furnace, including a bottom shell 1, in which a heating chamber 11 and a control chamber 12 are divided by a heat insulation plate 2, at least two heating furnace plates 3 are arranged in the heating chamber 11, and a mechanical control switch 4 electrically connected to the at least two heating furnace plates 3 with a single set of wires is arranged in the control chamber 12.

[0022] As shown in the accompanying drawings, a mechanical control switch 4 is used in this embodiment, such as a mechanical rotary coding switch, and each mechanical control switch 4 is electrically connected to the corresponding heating furnace plate 3 using only a single set of wires, which can realize separate control, and make the internal wiring simple and clear, and the external control is one-to-one simple and intuitive, which can simplify the assembly process while reducing the wiring cost and improve the assembly efficiency. At the same time, the heat insulation board 2 divides the inner cavity of the bottom shell 1 into two independent spaces, and the heating furnace plate 3 works in the heating cavity 11 and will not transfer heat to the control cavity 12, ensuring the normal working environment of the control switch, main control power board and other components in the control cavity 12. The number of heating furnace plates 3 is preferably four, and the specific size can be set as two large and two small diagonal settings as shown in the accompanying drawings, so that the overall size of the electric heating furnace will not be too large, and the placement of pots during use is also more reasonable. Example

[0023] The present embodiment also includes a glass panel 5 covering the surface of the bottom shell 1 , and the bottom surface of the heating chamber 11 is clamped with an elastic bracket 6 supporting the heating furnace plate 3 , and the elastic bracket 6 elastically presses the heating furnace plate 3 upwards and makes the heating furnace plate 3 elastically press against the glass panel 5 .

[0024] As shown in the accompanying drawings, the elastic bracket 6 is directly inserted into the hole pre-opened on the bottom shell 1, which is easy to install. The heating furnace plate 3 is placed on the elastic bracket 6, and the elastic bracket 6 pushes the heating furnace plate 3 upward to make it close to the bottom surface of the glass panel 5, so that the heat of the heating furnace plate 3 can be transferred to the glass panel 5 as much as possible, and at the same time, the heat of the heating furnace plate 3 can be reduced from overflowing from the heating cavity 11 to the outside and wasted. Example

[0025] In this embodiment, a latch hole 13 is provided on the bottom shell 1, and the elastic bracket 6 is L-shaped, including a transverse elastic support plate 61, a longitudinal baffle plate 62, and a hook 63 and an elastic clamping tongue 64 protruding from the bottom surface of the transverse elastic support plate 61. The hook 63 is inserted into the latch hole 13 and hooks the edge of the latch hole 13 in reverse, and the elastic clamping tongue 64 is inserted into the latch hole 13 and clamps the edge of the latch hole 13.

[0026] As shown in the accompanying drawings, each heating furnace plate 3 is provided with three elastic brackets 6, which can be made of thin plates. The front end of the transverse elastic support plate 61 is bent upward, so that it has a better upward rebound force when subjected to the downward pressure of the heating furnace plate 3. The three longitudinal baffles 62 respectively apply a clamping force to the side wall of the heating furnace plate 3, thereby ensuring that the top surface of the heating furnace plate 3 is steadily pushed against the glass panel 5. The end of the hook 63 is wider than the width of the clamp hole 13, and can be inserted laterally and then rotated to hook the edges on both sides of the clamp hole 13 during installation. The elastic clamping tongue 64 is arranged relative to the hook 63, and is folded in the opposite direction relative to the extension direction of the transverse elastic support plate 61. Its width is smaller than the width of the clamp hole 13. After inserting into the clamp hole 13 and then moving laterally, it can clamp and press the end edge of the clamp hole 13. As the heating furnace plate 3 pushes the longitudinal baffle 62 laterally, the elastic clamping tongue 64 clamps the clamp hole 13 more firmly. Example

[0027] In this embodiment, the glass panel 5 is square and connected to the edge of the bottom shell 1 via L-shaped connecting plates 51 fixed on all sides. A gap 52 is left between the glass panel 5 and the bottom shell 1 at the end of the L-shaped connecting plate 51.

[0028] As attached Figure 6 and Figure 8 As shown, the top surface of the L-shaped connecting plate 51 arranged in a 7-shape is fixed to the bottom surface of the glass panel 5, and the side surface is connected to the edge of the bottom shell 1 so that the glass panel 5 is higher than the upper edge of the bottom shell 1, and the length of the L-shaped connecting plate 51 is shorter than the edge length of the bottom shell 1, so that a gap 52 is left outside the two ends of the L-shaped connecting plate 51 for the exchange of air inside and outside the furnace. At the same time, the L-shaped connecting plates 51 around the periphery play the role of stably supporting the glass panel 5 to prevent the bottom surface of the glass panel 5 from being damaged due to local pressure. Example

[0029] In this embodiment, the heat insulation board 2 includes a hollow heat insulation frame 21 connected to the bottom shell 1 and a heat insulation strip 22 on the top, and the heat insulation strip 22 elastically presses against the glass panel 5.

[0030] As shown in the accompanying drawings, the hollow insulation frame 21 has a good insulation effect. The insulation strip 22 on the top presses against the glass panel 5 to prevent the heat in the heating chamber 11 from being transferred to the control chamber 12, thereby ensuring the normal working environment of components such as the control switch and the main power board in the control chamber 12.
