Plastic package motor for range hood

Abstract

A plastic package motor for a range hood belongs to the technical field of motors. The plastic package motor comprises a plastic packaging cover, a transmission shaft movably sleeves the right face of the plastic packaging cover, the outer wall of the left end of the transmission shaft and the left face of the plastic packaging cover are in a movable sleeving relation, fan blades movably sleeve the outer wall of the left end of the transmission shaft, a metal cover movably sleeves the right end of the transmission shaft, and the outer wall of the left end of the metal cover is fixedly sleeved in the right face of the plastic packaging cover. A metal sleeve plate is arranged under the plastic packaging cover, the right end of the metal sleeve plate is fixedly sleeved on the outer wall of the metal cover, the top surface of the left end of the metal sleeve plate is attached to the bottom side wall of the plastic packaging cover, the front and rear surfaces of the left end of the metal sleeve plate are fixedly connected with metal clamping rings; the left surface of the left end of the metal sleeve plate is fixedly connected with a metal ring; the upper and lower inner walls of the metal ring are fixedly sleeved with seven metal pipes; and the outer walls of the seven metal pipes are fixedly sleeved with the heat dissipation fins, thereby effectively achieving the heat dissipation of the interior of the plastic package motor, and improving the safety and stability of the plastic package motor in long-time work.

Description

Technical field [0001] The present invention belongs to the technical field of electrical equipment, in particular, to a plastic hood with a motor. Background technique [0002] Plastic motor is plastic packaging techniques motor stator core, winding, etc. overall package with plastic, metal chassis cancel conventional motor stator insulation treatment process and ordinary motor. Such micro motor fan been applied by the vacuum cleaner, range hoods, air conditioners, washing machines and other household appliances and instruments. At home and abroad to develop and produce plastic motor's a growing concern, because it has a number of advantages that are not metal housing motor and prospects. But because of the plastic motor insulation thermal insulation properties, which makes plastic motor itself is difficult to dissipate heat generated during operation, especially plastic motor in a long time, the internal plastic motor will generate a lot of heat, if heat can not be timely, plas...

AI Technical Summary

Problems solved by technology

However, the current plastic-enclosed motor has the characteristics of heat insulation, which makes it difficult to dissipate the heat generated by the plastic-enclosed motor itself, especially when the plastic-enclosed motor works for a long time, a large amount of heat will be generated inside the plastic-enclosed motor. The inability to dissipate heat in time not only reduces the stability of the plastic-sealed motor but also reduces the safety of the plastic-sealed motor when it is used. Therefore, there is an urgent need for a plastic-sealed motor for range hoods to solve the above problems
