Abstract

PURPOSE:To obtain the titled hoses of various inner diameters containing electric heating wires arranged at a fixed interval at a low cost by such an arrangement wherein a beltlike member of electric insulation having a receptive stripe, inserting stripe and holding stripe is spirally wound around a cylindrical member and the inserting stripe is gradually caused to couple with the dovetail groove of the receptive stripe. CONSTITUTION:A flexible and soft beltlike member 1 made of electric insulation on which a receptive stripe 2 having a dovetail groove 5, an inserting stripe 3 to be coupled with said dovetail groove 5 and a holding stripe 4 for holding an electric heating wire 6 are formed is used as a base material. While the beltlike member 1 is being spirally wound around along the outer surface of a cylindrical member 7, the inserting stripe 3 is gradually caused to couple in the dovetail groove 5 of the receptive stripe 2 and by this, a hose 8 is obtained. It is made possible to obtain a hose having a different inner diameter by simply changing the outer diameter of a cylindrical member.

(b) Background technology and its problems Generally, hoses with heating wires, which are used in refrigeration and air conditioning equipment for the purpose of preventing drains from freezing or keeping fluids warm, have a heating wire attached to the outer surface of the rubber cylindrical member that serves as the core material. After winding a heating wire such as a silicone heater in a spiral, a net-like tape is wound spirally to cover the heating wire, and then the band-shaped rubber is heated to a vulcanized state and turned into a tape using a jig. It is manufactured through various steps of impregnating it and transforming it into a cylindrical shape to form a protective cylinder.

According to this manufacturing method, the intervals between the heating wires tend to be uneven, and the steps for winding the heating wires and tape, forming the protective tube, and protecting the heating wires are increased, and the material cost is high. This not only leads to higher manufacturing costs, but also because the inner diameter of the hose itself is determined, so when producing hoses with different inner diameters, separate processes had to be carried out.

(c) An object of the present invention is to inexpensively manufacture a hose containing heating wires in which the distance between the heating wires is constant and the outer diameter of the cylindrical member is varied in length and inner diameter.
