DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 10 The present invention provides a technical solution for a warm vegetable plate.

[0020] like Figure 1-Figure 7 As shown, a food warming plate includes a heating plate body 1, a heating wire 3 is installed in the heating plate body 1, and the heating wire 3 includes: The first heating part 31 includes a plurality of first vertical parts 311 arranged in parallel with each other and a first connecting part 312 connected between adjacent first vertical parts 311, the first vertical parts 311 are perpendicular to the curling direction A of the heating plate body 1, the first heating part 31 includes a first heating proximal end 313 and a first heating distal end 314, the first heating proximal end 313 is close to the control box 4 of the warming plate, and the first heating distal end 314 is far away from the control box 4 of the warming plate; The second heating part 32 includes a plurality of second vertical parts 321 arranged in parallel with each other and a second connecting part 322 connected between adjacent second vertical parts 321, the second vertical part 321 is perpendicular to the curling direction A of the heating plate body 1, the second heating part 32 includes a second heating proximal end 323 and a second heating distal end 324, the second heating proximal end 323 is close to the control box 4 of the warming board, the second heating distal end 324 is far away from the control box 4 of the warming board, the first heating distal end 314 is connected to the second heating distal end 324, and the first heating part 31 and the second heating part 32 are symmetrically arranged.

[0021] Since the first vertical portion 311 and the second vertical portion 321 are perpendicular to the curling direction A of the heating plate body 1, the first vertical portion 311 and the second vertical portion 321 will not be curled during the curling process of the heating plate body 1, thereby avoiding curling of a long length of the heating wire 3, increasing the service life of the heating wire 3, and facilitating the curling operation, thereby improving the user experience.

[0022] A control box 4 is also fixed on the heating plate body 1 , and the first heating proximal end 313 and the second heating proximal end 323 are connected to the control box 4 .

[0023] like Figure 8 As shown, this is an installation method of the heating wire 3, the heating wire 3 is embedded in the heating plate body 1, and the heating wire 3 and the heating plate body 1 are formed in one piece. Since the heating wire 3 is directly fixed (embedded) in the heating plate body 1 (the heating wire 3 and the heating plate body 1 are integrated), no additional gluing or other methods are required to fix it, so there is no gap between the first heating wire 3 and the silica gel body, the product is more beautiful, and the production cost is low.

[0024] A supporting foot 2 is fixed to the lower side of the heating plate body 1 , and the supporting foot 2 can play the role of the heating plate body 1 .

[0025] like Figure 1-7 As shown, another installation method of the heating wire 3 is provided, the upper side of the heating plate body 1 is provided with a winding groove 5 with an opening facing upward, the shape of the winding groove 5 corresponds to the shape of the heating wire 3, the heating wire 3 is installed in the winding groove 5, and the upper side of the heating plate body 1 is fixed with a heat conductive sheet 6 in contact with the heating wire 3. The heat conductive sheet 6 is preferably made of metal.

[0026] Since the heat conducting sheet 6 is in direct contact with the heating wire 3, the heat conducting efficiency is high, the heat conducting sheet 6 can withstand higher temperatures, and the heating temperature of the whole warming plate can be increased, thereby improving the user experience. Furthermore, since the heat conducting sheet 6 transfers heat, its heat efficiency is high and the heat loss is small, and the power can be reduced compared to conventional silicone warming plates, thereby achieving energy saving.

[0027] A flange 7 is provided around the heat conducting plate 6, and a first glue groove 8 corresponding to the flange 7 is provided on the upper side of the heating plate body 1. The flange 7 is plugged into the first glue groove 8, and the flange 7 is fixed in the first glue groove 8 by glue.

[0028] The upper side of the heating plate body 1 is provided with a groove 9 corresponding to the heat conducting sheet 6, and the heat conducting sheet 6 is plugged into the groove 9. The upper side of the heat conducting sheet 6 and the upper side of the heating plate body 1 are in the same plane, which can make the upper side of the warm food board smoother and more convenient to use.

[0029] A plurality of heat-conducting sheets 6 are arranged in sequence along the curling direction of the heating plate body 1 , so that the heat-conducting sheets 6 will not affect the curling of the heating plate body 1 .

[0030] The lower side of the heating plate body 1 is provided with a plurality of wire grooves 10 connected with the winding grooves 5 . After winding, glue is applied to the wire grooves 10 to better fix the heating wires 3 .

[0031] like Fig. 9 and Fig.10 As shown, it is another installation method of the heating wire 3, and the heating plate body 1 includes: A lower silicone plate 11, wherein the upper side of the lower silicone plate 11 is provided with a lower winding groove 12, the shape of the lower winding groove 12 corresponds to the shape of the heating wire 3, and the heating wire 3 is installed in the lower winding groove 12; The upper silicone plate 13 is fixed to the upper side of the lower silicone plate 11 , and the heating wire 3 abuts against the lower side of the upper silicone plate 13 .

[0032] When the heating wire 3 is installed in the lower winding groove 12, it protrudes out of the lower winding groove 12, and the upper silicone plate 13 is fixed on the upper side of the lower silicone plate 11. Since the upper silicone plate 13 and the lower silicone plate 11 have a certain elasticity, the heating wire 3 is ensured to be in close contact with the lower side of the upper silicone plate 13, thereby increasing the heat transfer efficiency.

[0033] Two second glue grooves 14 are provided on the lower side of the upper silicone plate 13, and the two second glue grooves 14 are located on both sides of the lower winding groove 12. Glue is installed in the second glue grooves 14, and the upper silicone plate 13 and the lower silicone plate 11 are fixed together by glue. This arrangement can firmly connect the lower silicone plate 11 and the lower winding groove 12 of the upper silicone plate 13 together, and prevent the heating wire 3 from moving out of the lower winding groove 12.

[0034] The lower side of the upper silicone plate 13 is provided with an outer glue groove 15, and the lower winding groove 12 is located in the outer glue groove 15. Glue is installed in the outer glue groove 15, and the upper silicone plate 13 and the lower silicone plate 11 are fixed together by glue, thereby increasing the firm connection between the lower silicone plate 11 and the upper silicone plate 13.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
