Description

Technical Field

[0001] The utility model particularly relates to a steel pipe heater with a fixed bracket for a drying channel of a clothes dryer. Background Art

[0002] The main function of the dryer is to heat the air through a resistance wire or other heating element, and then send the hot air into the drum of the dryer to accelerate the evaporation of wet clothes, thereby achieving a quick drying effect. This heater is usually composed of a series of steel pipes with resistance wires installed inside. When the current passes through the resistance wire, the heat generated will be conducted to the surface of the steel pipe, and then the heat will be transferred to the air flowing through the pipe. The main structure of the steel pipe heater for the dryer is usually made of stainless steel or other high-temperature resistant materials to ensure stability and durability under high-temperature operation.

[0003] In order to improve the heat transfer efficiency, the existing dryer heater will make a double-layer heating tube from a single layer. However, there is no good retaining device between the upper and lower layers of the double-layer heating tube, which is prone to shaking. Since the upper and lower layers are close to each other, they will also contact and collide with each other due to external forces, causing damage. It is not convenient to stably fix the double-layer heating tube. In addition, the end of the double-layer heating tube is not easy to quickly connect with the dryer shell through a flange. For this reason, we propose a steel tube heater for a dryer drying channel with a fixed bracket. Utility Model Content

[0009] Preferably, the retaining mechanism includes a first positioning plate, a second positioning plate, a pipe clamp and a limiting bolt. The first positioning plate and the second positioning plate are arranged side by side, and the pipe clamp is respectively fixed to the side walls of the first positioning plate and the second positioning plate. The recesses of every two adjacent pipe clamps correspond to the heating steel pipe. The limiting bolt is arranged at one end of the inner side of the first positioning plate, and the other end of the limiting bolt cooperates with the second positioning plate.
