Abstract
The utility model discloses an indoor and outdoor machine connection pipe which at least comprises a corrugated pipe section in a C shape. A corrugated pipe section is replaced by the C-shaped corrugated pipe section, the crest and trough positions of the C-shaped corrugated pipe section can be directly made up through transverse extension of materials, and deformation at the crest and trough positions of a spiral corrugated pipe is made up through longitudinal deformation of the materials, so that use amount of the materials is reduced, and production cost is reduced. The change of the crest and the trough of the C-shaped corrugated pipe section tends to be gentle, stress is dispersed and distributed, wall thickness is high in consistency, and a product is reliable in quality. When external force is exerted on the C-shaped corrugated pipe section, the direction of acting force is changed by changing the wave shape, so that a pressing-resistant value and bending-resistant times of the product can be increased, and product quality is improved. The utility model further discloses an air conditioner provided with the indoor and outdoor machine connection pipe.
