Examples
As shown in fig. 1, the present embodiment provides a method for manufacturing a collector rack, comprising the steps of:
s00: and (5) processing the energy-gathering pot frame body. Wherein, the energy-gathering wok stand body is the wok stand that does not carry out the protection and handles, and the energy-gathering wok stand body includes interconnect's upper cover 500 and lower floor's cover 100, forms the cavity between upper cover 500 and the lower floor's cover 100, and the cavity intussuseption is filled with the air, and upper cover 500 and lower floor's cover 100 adopt stainless steel to process usually to form, and specific upper cover and lower floor's cover 100 accessible circumference edge welded mode are connected.

s3 heat treatment: and carrying out heat treatment on the energy-gathering pot holder body coated with the protective coating, so that the protective coating forms a protective layer on the energy-gathering pot holder body to obtain the energy-gathering pot holder.
According to the manufacturing method of the energy-gathering pot holder, the through hole 300 is formed in the energy-gathering pot holder body, then the protective coating is coated on the energy-gathering pot holder body, and the protective layer is formed through heat treatment, so that the energy-gathering pot holder is obtained. In the heat treatment process, air in the cavity between the two layers of the energy-collecting pot frame body can be communicated with the outside, so that the energy-collecting pot frame body is prevented from being deformed due to the change of air pressure in the inner cavity in the heat treatment process, and the shape stability of the energy-collecting pot frame body in the process of forming a protective layer is ensured; and because the pot frame is not easy to deform, the protective layer can not crack and other problems caused by the deformation of the pot frame, and the yield of the protective layer is improved. Therefore, the production qualification rate of the whole energy-gathering pot frame is improved, the consumables are saved, the rework rate of the defective products is reduced due to the reduction of the defective products, and the production efficiency is improved.
Specifically, the step of applying the protective coating at S2 may be to uniformly spray the protective coating on the surface of the collector body provided with the through-hole 300.

Specifically, the step of S01 roughening treatment includes: and spraying the emery to the surface of the energy-collecting pot frame body to roughen the surface of the energy-collecting pot frame body.
Wherein, the main component of the carborundum is carborundum. When the material of the energy-collecting pot holder body is stainless steel, 80-160 meshes (specifically, one or more of 80 meshes, 100 meshes, 120 meshes, 140 meshes and 160 meshes) of carborundum can be sprayed in the roughening treatment process, so that the surface of the energy-collecting pot holder body can meet the requirement of the coating roughness of a proper enamel raw material mixture.
It can be understood that the step of roughening the through hole 300 in S01 is performed before the step of processing the through hole 300 in S1, so that the method can prevent the generated debris from entering the through hole 300 during roughening, save the step of removing the impurities from the through hole 300, ensure the cleanliness of the through hole 300 after the through hole 300 is processed, and facilitate the improvement of the production efficiency. Meanwhile, the roughening treatment can improve the adhesion capability of the protective coating on the surface of the energy-collecting pot holder body, so that the protective coating can form a certain thickness on the surface of the energy-collecting pot holder body, and the thickness of a subsequently formed protective layer meets the requirement. In this embodiment, the thickness of the protective layer in the form of an enamel layer may be between 0.1 mm and 0.4 mm; the linear expansion coefficient of the protective layer is 90 x 10-4/℃～105×10-4/℃。
In the manufacturing method of the energy collecting pot holder of the embodiment, the step of processing the through hole 300 by the S1 is specifically: the lower layer cover 100 of the energy collecting pot frame body is provided with a through hole 300.
As shown in fig. 2 and 3, the lower cover 100 of the concentrator body of the present embodiment refers to a cover body that is disposed away from the cooker, facing the cooktop surface. The through hole 300 communicating with the cavity of the concentrator body may be formed by drilling a hole in the lower cover 100 of the concentrator body. The through hole 300 is arranged on the lower layer cover 100 of the energy-gathering pot holder body, when the energy-gathering pot holder is used, the through hole 300 is not exposed in a visual field range, and the attractiveness of the energy-gathering pot holder is not affected.
In the present embodiment, a through hole 300 is formed in the surface of the lower cover 100 of the collector body on which the leg piece 200 is provided.
Referring to fig. 3, a three-dimensional view of a power concentrating pan rack placed approximately upside down is shown, the power concentrating pan rack comprises a circular arc-shaped surface 101 extending in an arc shape along the vertical direction and a circular ring part 102 arranged in the middle of the circular arc-shaped surface 101, the shape of the lower layer cover 100 is consistent with that of the power concentrating pan rack, the foot piece 200 is used for supporting the power concentrating pan rack and arranged on the circular arc-shaped surface 101 of the lower layer cover 100, and the through hole 300 is also arranged on the circular arc-shaped surface 101.

In this embodiment, the aperture of the through hole 300 is determined to be 4 mm to 6 mm by combining the manner of sealing the through hole 300 with the sealing member 400 such as silicone rubber or rubber. It can be understood that when the diameter of the through-hole 300 is less than 4 mm, it is inconvenient to exhaust air in time, and when the size of the through-hole 300 is greater than 6 mm, it is easy to affect the sealability of the sealing member 400 to the through-hole 300.
The manufacturing method of the energy collecting pot rack of the embodiment further comprises the following steps: the preparation of the protective coating is that the enamel raw materials are mixed according to the installation proportion to form a mixture.
