AI Technical Summary

Technical Problem

Due to poor versatility of existing air conditioners, the volute structure needs to be redesigned according to the installation space of different sizes, resulting in extended R&D cycle, improved production costs and reduced production efficiency.

Method used

A volute shell structure is designed, including a volute cover plate, a volute shell and a volute tongue. Through a sliding connection structure, the volute can move radially, adjusting the space of the volute air duct, thereby adapting to installation spaces of different sizes.

Benefits of technology

The volute structure is highly versatile, and can adjust the position and air volume according to the size of the installation space, reduce production costs, and improve production efficiency. It is suitable for fresh air components of different products.

Abstract

The present invention relates to a volute structure, a fan, a fresh air device and an air conditioner, and relates to the technical field of air conditioning equipment. It solves the problem in the prior art that due to the poor versatility of fresh air components, in order to adapt to installation spaces of different sizes, the volute structure usually needs to be redesigned, which increases the research and development cycle and increases the production cost. The volute structure includes a volute cover plate, a volute and a volute tongue. The two volute cover plates are connected by the volute and the volute tongue, and the volute cover plate, the volute and the volute tongue surround a volute air duct. An active connection is formed between the end of the volute away from the volute tongue and the volute cover plate. The volute profile can be adjusted by the active connection under the influence of the size of the space, so that the volute can move along the radial direction of the volute structure to change the space of the volute air duct. The versatility is strong, and the volute position can be adjusted according to the size of the installation space to adapt to different installation spaces, so that the fresh air component with the volute structure can be adapted to different products, reducing the production cost.
