Background technique

The hot air blower is the first choice for modern industrial heat source upgrading. The electromechanical equipment is the best hot air source configuration for automatic machinery such as hot air conveying furnace, drying furnace, oven, packaging machine and so on. The hot air fan is composed of three parts: the blower, the heater and the control circuit. It realizes the regulation of the working temperature and the air volume. At present, the main principle of the hot air fan in the market is that the axial fan sucks the air, and then directly blows it out after being heated by the PTC heating body. Although its structure is simple, it has the following shortcomings: PTC heating element itself is conductive and non-waterproof, PTC is exposed to the outside, it is easy to enter the water, resulting in electric shock hazard; the device can only be used for a single purpose, the function expandability is poor.

At present, the principle of the heating drying racks on the market is that the clothes are hung on the drying rack, and the drying rack is heated by the heating wire, so that the clothes hanging on the drying rack are heated and dried. However, such heat-generating drying racks have the following disadvantages: First, the heating and drying efficiency is low: because the heating device is used to heat the drying rack and then heat the clothes in contact with the drying rack, the heating area is small, the heat conduction diffusion speed is slow, and the drying efficiency is low; Second, uneven drying: Because the heat spreads from the location where the clothes are in contact with the clothes rack, it will cause the clothes to dry slowly at the end away from the clothes rack, resulting in extremely uneven drying conditions. Third, a single function: the existing clothes rack In addition to being able to dry clothes, it is difficult to use for other purposes and has a single function.
