Scroll casing and clothes drying machine

Abstract

The invention aims at providing a scroll casing and a clothes drying machine. The scroll casing can be formed by different parts through combination, the processing difficulty is reduced, the product precision is high, the pneumatic loss caused by the airflow collision can be reduced, and the noise is lower. The scroll casing is made of plastic materials, so the material cost is saved. At the same time, a wind outlet of the scroll casing can not be shielded by a grid device, the pneumatic loss caused by the airflow collision can be reduced, the noise is lower, simultaneously, the protective effect on the inside of a machine body is good, and the occurrence of the situation of collision between the grid device and a fan can not be caused. The invention is realized through the following technical scheme: the scroll casing comprises a bottom plate, a rotary step-shaped scroll curve surface casing, a scroll curve surface and a wind outlet, a space inside the scroll curve surface is an air flowing region, the scroll casing is divided into two or more than two mutually dismountable assemblies, the assemblies are in split joint through connecting devices for forming the whole body of the scroll casing, and two or more than two assemblies are all plastic structural elements.

Description

technical field [0001] The invention belongs to the field of home appliances, and in particular relates to a structure of a volute part in a clothes drying device for drying wet clothes and articles. Background technique [0002] Most of the currently widely used clothes dryers use electric heating, steam heating, hot air heating, hot water heating and other simple energy exchange methods to dry wet clothes and articles. These several heating modes consume a lot of energy, have low drying efficiency, and take a long time. At the same time, after the clothes are piled up and dried in the machine, they are easy to wrinkle, and the clothes fibers are easily damaged due to uneven heating. Heat pump technology is a technology that generates heat by compressing air to cause a phase change. Using heat pump technology for heating can greatly save energy. The heat pump is essentially a heat raising device. The function of the heat pump is to absorb heat from the surrounding environ...

Problems solved by technology

The closing part is usually a grille device that can close the air outlet of the air duct. The grille device is partially located inside the air duct and can completely cover the air outlet of the air duct, but occupies the inner space of the air duct and affects the air outlet. At the same time, the distance between the grille device and the fan is close. After long-term operation or when there is an error in the assembly accuracy, it is easy to cause the collision between the grille device and the fan.
