The base has an insulation layer inside, the heating plate is placed on the insulation layer, and the panel covers the heating plate. Side frames surround the panel on the upper surface of the base, with gaps between the side frames and the panel. A groove is provided in the insulation layer directly below the gap. The groove has a U-shaped structure, and several second drainage holes are provided at the bottom of the groove. First drainage holes, corresponding one-to-one with the second drainage holes, are provided at the bottom of the base. A U-shaped collection trough is also provided inside the groove, and third drainage holes, corresponding one-to-one with the second drainage holes, are provided at the bottom of the collection trough. A support platform for placing the heating plate is formed in the center of the insulation layer.
[0006] Furthermore, the side border includes two long side borders and two short side borders, which together form a rectangular border.
[0007] Furthermore, the panel is provided with a vertically arranged first side baffle around its perimeter, and a vertically arranged second side baffle is provided on the long side frame and the short side frame respectively, with a gap between the first side baffle and the second side baffle.
[0008] Furthermore, a controller connected to the heating plate is also provided on the side wall of the base.
[0009] Furthermore, the base is equipped with support legs at the bottom.
[0010] Furthermore, a removable water collection tank is provided at the bottom of the base, and the water collection tank is located below the first drain hole.
[0011] Furthermore, a slot for inserting a water collection tank is provided at the bottom of the base.
[0012] Compared with existing technologies, the temperature-controllable electric heating plate of this invention has the following advantages:
[0013] The temperature-controllable electric heating plate of this utility model has a heat insulation layer with a groove facing the gap between the side frame and the panel. A collection tank is provided in the groove. When liquid is spilled, the liquid can flow into the collection tank along the gap and be discharged through the third drain hole, the second drain hole and the first drain hole, so as to avoid excessive liquid accumulation on the surface of the electric heating plate.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] like Figure 1-6 As shown, a temperature-controllable electric heating plate includes a base 1, a heating plate 2, a panel 3, an insulation layer 8, and a side frame. The insulation layer 8 is provided inside the base 1, the heating plate 2 is placed on the insulation layer 8, and the panel 3 covers the top of the heating plate 2. The upper surface of the base 1 is surrounded by a side frame around the panel 3, and a gap is left between the side frame and the panel 3. The insulation layer 8 directly below the gap has a groove 81, which is in the shape of a U-shape. The bottom of the groove 81 has several second drainage holes 82, and the bottom of the base 1 has first drainage holes 11 corresponding to the second drainage holes 82. The groove 81 also has a U-shaped collection groove 84, and the bottom of the collection groove 84 also has third drainage holes 85 corresponding to the second drainage holes 82. A support platform 83 for placing the heating plate 2 is formed in the center of the insulation layer 8.
[0028] The insulation layer has a groove facing the gap between the side frame and the panel. A collection tank is provided in the groove. When liquid is spilled, it can flow into the collection tank along the gap and be discharged through the third drain hole, the second drain hole and the first drain hole, avoiding excessive liquid accumulation on the surface of the heating plate.
[0029] For example, the side border includes two long side borders 5 and two short side borders 4, which together form a rectangular border.
[0030] Specifically, the panel 3 is provided with a vertically arranged first side baffle 31 around its perimeter, and the long side frame 5 and the short side frame 4 are provided with vertically arranged second side baffles 51 respectively, with a gap between the first side baffle 31 and the second side baffle 51.
[0031] The first and second side baffles prevent liquid from flowing along the lower surface of the panel to the heating plate. At the same time, the first and second side baffles act as guides, directing the liquid into the collection tank.
[0032] For example, a controller 7 connected to the heating plate 2 is also provided on the side wall of the base 1. The controller adopts a temperature control device commonly used in the prior art.
[0033] For example, the base 1 has a support leg 6 at its bottom.
[0034] For example, a detachable water collection tank 9 is provided below the base 1, and the water collection tank 9 is located below the first drain hole 11.
[0035] Specifically, a slot 12 for inserting a water collection tank 9 is provided at the bottom of the base 1.
[0036] The collection tank facilitates the collection of outflowing liquid for centralized treatment.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
