Water drain soft pipe

Abstract

Provided is a drain hose allowing the stable fitting of an outer tubular member for insulation and also the stable connection by increasing the deformation strength of a connection tubular body connected to a drain port.In this drain hose 1 formed by fitting the connection tubular body 4 connected to the drain outlet 3 of an air conditioner to one end of a hose body 2 covered by the outer tubular member 40 for insulation. A binding member 45 fastening the end part of the outer tubular member 40 from the outside is fitted into an annular recessed groove 32 formed on the outer peripheral surface side of the connection tubular body 4. Thus, the physical binding thereof with the outer tubular member 40 is increased, and the outer tubular member 40 can be stably installed. In addition, since the strength of the recessed groove 32 portion is increased, the deformation strength of the connection tubular body 4 can be increased.

Description

technical field [0001] The present invention mainly relates to a drain hose connected to a condensed water discharge port of an indoor unit of an air conditioner or the like. Background technique [0002] The drain hose in the prior art is generally formed at one end of the flexible serpentine hose body integrally into a connecting cylinder that can be embedded and connected to the condensed water outlet of the indoor unit. [0003] Moreover, in such drain hoses, as disclosed in Patent Documents 1 and 2, in order to prevent problems such as condensation on the outer peripheral surface of the hose body, a heat-insulating outer cylinder member is used to cover the hose body. on the outer peripheral surface. [0004] Patent Document 1: Japanese Publication No. 54-126215 [0005] Patent Document 2: Japanese Patent Laid-Open No. 2000-234756 [0006] However, in the prior art drain hose that uses a heat-insulating outer tube member to cover the outer peripheral surface of the h...

Problems solved by technology

But for this occasion, especially for the occasion where the thickness of the drain hose is relatively thin, the weight is relatively light and has flexibility, when the front end of the connection side is in contact with the drain pipe to prevent it from further tilting, the connection port of the connecting cylinder is easy to use. The front end of the connection side becomes a fulcrum and deforms into an ellipse, which probably promotes the deformation instead, so this configuration cannot be considered as an effective configuration.
