Description of reference numerals: the air conditioner comprises a machine shell 1, an air outlet pipe 2, an outer pipe 21, an upper pipe 221, a lower pipe 222, a fastening ring 3, an upper clamping plate 41, a lower backing plate 42, a pin rod 431, a fixing groove 432, a flow plate 5 and a sealing gasket 6.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

1-3, including casing 1 and outlet duct 2, outlet duct 2 is by outer tube 21, upper tube 221 and low tube 222 constitute, upper tube 221 and low tube 222 activity nestification are in the inner chamber of outer tube 21, and can be relative outer tube 21 dismouting, the externally mounted of upper tube 221 and low tube 222 has the tight loop 3 of fixing relative outer tube 21 with the two component, tight loop 3 can dismantle the suit at upper tube 221, the outside of low tube 222 component, through outer tube 21 and upper tube 221, detachable outlet duct 2 that low tube 222 constitutes, because of giving the air inlet in outlet duct 2, when exhaust causes upper tube 221 and low tube 222 to damage, carry out instant change to the two, when guaranteeing its normal work, very big reduction the replacement cost.

The fastening ring 3 is provided with a notch which enables the fastening ring to be detachable, an upper clamping plate 41 and a lower backing plate 42 are installed on opposite surfaces of two ends of the notch, the upper clamping plate 41 and the lower backing plate 42 are relatively embedded to enable the upper pipe 221 and the lower pipe 222 to be fixed relative to the outer pipe 21, and through the combined action of the upper clamping plate 41 and the lower backing plate 42, the upper pipe 221 and the lower pipe 222 are annularly fixed on the outer portions of the upper pipe 221 and the lower pipe 222 along the installation direction of the upper pipe 221 and the lower pipe 222, so that the fixing strength between the outer pipe 21 and the upper pipe 221 and the lower pipe.
