Feel like a common electric fan. For common air-conditioning fans or heaters, the air should be cooled or heated in the machine body and then blown out of the machine by the fan to achieve the purpose of cooling or heating. In order to obtain a certain ventilation, cooling or heating effect, the wind speed and air volume of these devices must reach a certain value. In other words, they must have a certain power. The smallest mini-type device has a single fan power of more than ten watts. Technology These fans are driven by AC power (the field is not included in the "home air conditioning unit" referred to here), and all such devices are all equipped with inner rotor motors, the blades of the blades relative to the outer ring Movement, separated from each other, so the size of the fan is very large, 'even the mini fan has an axial dimension of 50 mm or more. In addition to the axial flow type, the fan type of the existing household air conditioner has a large number of cross-flow type and centrifugal type, and the size of the fan is even larger. Due to the size of the fan, these devices are very large in size, and the axial thickness is rarely less than 100 mm. It not only takes up a lot of space, but also consumes more plastic and metal materials. The AC wire consumption of the AC motor used is even more amazing. And the power consumption is high. Due to the high penetration rate of household air-conditioning devices such as electric fans, air-conditioning fans, and heaters, the high consumption of resources leads to the consumption of resources, which greatly restricts the development of the national economy, increases the manufacturing costs of manufacturers, and also brings heavy weight to consumers. The burden. In order to reduce the axial dimension, there are very few electric fan designs that simply combine multiple small fans, but because it is a plurality of independent electric fans mechanically arranged together, the cost is higher. On the other hand, the control performance of AC motors is very poor, and the shifting is difficult. The AC motors used in household appliances can only achieve three-stage speed regulation at most, making it difficult to achieve stepless speed regulation. The AC motor is driven by 220V mains, which has poor safety. It must use reinforced insulation and safety protection measures, which further increases the production cost.
