Carbon fiber tube preparing method and baking tube and microwave oven

Abstract

The invention discloses a carbon fiber tube preparing method, which includes steps of increasing spindle number of a carbon fiber knitting machine, adjusting drawing distance and knitting carbon fibers to form a carbon fiber tube with the closed surface. The invention further discloses a baking tube and a microwave oven, which utilize the carbon fiber tube. The carbon fiber tube has excellent strength and is lower in requirements for later curing treatment of carbon filaments, and simultaneously, radiation filaments can be thinner or shorter on the premise that the closed knitted structure can keep constant radiant power. The baking tube provided with the carbon fiber tube is smaller in size, the carbon fiber tube has excellent interface property so that sparking can be reduced when the carbon fiber tube acts with microwaves and quality of the baking tube is improved further. Installing space of the baking tube in the microwave oven provided with the baking tube can be effectively reduced, so that the number of the baking tubes can be increased, and multi-directional multi-working-mode baking effect in an oven cavity is realized.

Description

technical field [0001] The invention relates to a preparation method of a barbecue tube, in particular to a preparation method using closed braiding, a barbecue tube prepared by the method and a microwave oven using the barbecue tube. Background technique [0002] figure 1 It is a partial structural perspective view of a microwave oven with barbecue function in the prior art. Such as figure 1 As shown, this prior art microwave oven 1 with grilling function mainly includes: an outer box body that constitutes the outer structure of the microwave oven not shown in the figure; a turntable that can be arranged inside the outer box body 7 is placed on the cooking chamber 2 of the food to be cooked; it is arranged on the other side of the outer casing, and the electric control room 4 of various electronic components such as a magnetron 3 and a high-voltage transformer not shown in the figure is installed in it. ; Installed on the grill tube assembly 5 on the top surface of the c...

AI Technical Summary

Problems solved by technology

[0005] However, due to the grid weaving process in the prior art of the carbon fiber tube, combined with insufficient carbon fiber strength and low weaving density, the overall strength of the electric heating core after weaving is insufficient, and it is difficult to ensure the coaxiality during packaging. The woven carbon fiber filaments are cured and the treatment process is relatively complicated, and the radiation surface area of ​​the existing weaving technology is small, and the radiation uniformity is poor
