Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the warm plate, concretely relates to a heating wire fixing structure and warm plate. BACKGROUND

[0002] The existing flexible silica gel warm plate is soft, and can be folded or curled for storage when not in use, thereby saving space. The flexible silica gel warm plate fixes the heating wire on the silica gel main body, the heating wire generates heat, and the heat is transferred to the silica gel main body, thereby achieving the heat preservation effect.

[0003] However, the existing silica gel warm plate uses the gluing method to fix the heating wire, that is, a wire winding groove is formed on the silica gel main body, the heating wire is filled into the groove, and then glue is applied on the surface to cover the heating wire. In this way, there is inevitably a gap between the heating wire and the wire winding groove, which leads to low heat transfer efficiency and large heat loss. In addition, the air in the gap will be heated and expanded, which causes the local bulging of the warm plate panel, thereby affecting the use effect and the appearance. UTILITY MODEL CONTENTS

[0008] Further, the first heating part comprises a first heating proximal end and a first heating distal end, the first heating proximal end is close to the control box of the warm plate, the first heating distal end is away from the control box of the warm plate,

[0009] The first heating wire further includes a second heating section, which comprises a plurality of parallel second vertical sections and a second connecting section connecting adjacent second vertical sections.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-8This utility model provides a heating wire fixing structure and a food warming board technical solution.

[0033] A heating wire fixing structure includes a silicone heating plate body 1, in which a first heating wire 2 is embedded, and the first heating wire 2 is integrally formed with the silicone heating plate body 1.

[0034] Since the first heating wire 2 is directly fixed (embedded) inside the silicone heating plate body 1 (the first heating wire 2 and the silicone heating plate body 1 become one), there is no need for additional glue or other methods to fix it. In this way, there is no gap between the first heating wire 2 and the silicone body, resulting in high heat transfer efficiency, a more aesthetically pleasing product, and low production costs. Example 1

[0035] The first heating wire 2 includes a first heating part 3, which includes several first vertical parts 4 arranged in parallel with each other and a first connecting part 5 connected between adjacent first vertical parts 4. The length of the first vertical part 4 is greater than the length of the first connecting part 5, and the first vertical part 4 is perpendicular to the curling direction A of the silicone heating plate body 1.

[0036] Since the first vertical part 4 is perpendicular to the curling direction A of the silicone heating plate body, the first vertical part 4 will not be curled during the curling process of the silicone heating plate body 1, thus avoiding the curling of a large length of the first heating wire, improving the service life of the first heating wire 2, and making the curling operation easier, thereby improving the user experience.

[0037] The first heating element 3 includes a first proximal heating end 6 and a first distal heating end 7. The first proximal heating end 6 is close to the control box 8 of the warming plate, and the first distal heating end 7 is away from the control box 8 of the warming plate. The first heating wire 2 also includes a first parallel part 9, which is parallel to the curling direction of the silicone heating plate body 1. One end of the first parallel part 9 is connected to the first distal heating end 7, and the other end is located near the control box 8 of the warming plate. With this arrangement, the first heating wire 2 can be connected to the control box 8.

[0038] The silicone heating plate body 1 has several support feet 15 on its lower side. When in use, the support feet 15 can support the silicone heating plate body 1 on a table. The support feet 15 are arranged in several rows, with the support feet 15 in adjacent rows being staggered.

[0039] like Figure 6 As shown, the distance between adjacent first vertical parts 4 is set to B, where 20mm≤B≤33mm.

[0040] The thickness of the silicone heating plate body 1 is set to C, where 2.5mm≤C≤3.3mm.

[0041] The height of support leg 15 is set to D, where 8mm ≤ D ≤ 15mm.

[0042] The distance between the upper tangent of the first heating wire 2 and the upper side of the silicone heating plate body 1 is set to A, where 2mm≤A≤2.3mm.

[0043] By designing the heating wire fixing structure with the above parameters, it has the effects of fast heat transfer efficiency and low heat loss.

[0044] like Figure 5 As shown, the lower side of the silicone heating plate body 1 is integrally formed with a protrusion 16, which corresponds to the shape of the first heating wire 2. Example 2

[0045] like Figure 7 and Figure 8 As shown, the arrangement of the first heating wire 2 in this embodiment is different from that in Embodiment 1. The first heating wire 2 includes a first heating part 3. The first heating part 3 includes several first vertical parts 4 arranged in parallel with each other and a first connecting part 5 connected between adjacent first vertical parts 4. The length of the first vertical part 4 is greater than the length of the first connecting part 5. The first vertical part 4 is perpendicular to the curling direction A of the silicone heating plate body 1.

[0046] The first heating element 3 includes a first heating proximal end 6 and a first heating distal end 7, with the first heating proximal end 6 close to the control box 8 of the warming plate and the first heating distal end 7 away from the control box 8 of the warming plate.

[0047] The first heating wire 2 also includes a second heating part 10, which includes a plurality of parallel second vertical parts 11 and a second connecting part 12 connecting adjacent second vertical parts 11. The second vertical parts 11 are perpendicular to the curling direction A of the silicone heating plate body 1.

[0048] The second heating element 10 includes a second heating proximal end 13 and a second heating distal end 14. The second heating proximal end 13 is close to the control box 8 of the warming plate, and the second heating distal end 14 is far away from the control box 8 of the warming plate. The first heating distal end 7 is connected to the second heating distal end 14. The second heating element 10 is symmetrically arranged with the first heating element 3.

[0049] Since the first vertical portion 4 and the second vertical portion 11 are perpendicular to the curling direction A of the silicone heating plate body, the first vertical portion 4 and the second vertical portion 11 will not be curled during the curling process of the silicone heating plate body 1, thus avoiding the curling of a large length of the first heating wire, improving the service life of the first heating wire 2, and making the curling operation easier, thereby improving the user experience.

[0050] A food warmer was also disclosed, which includes the aforementioned heating wire fixing structure.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
