The present invention relates to a vacuum cleaner hose produced by inserting an electric wire into a target material to be molded and extruded and adhesively wound in a spiral shape.

In general, a hose for a vacuum cleaner has a current-carrying function of transmitting power to a motor by inserting an electric wire into a hollow protrusion of a target material molded and diced by a die so as to have an uneven section shape at a predetermined interval. .

In this vacuum cleaner hose, two wires supplying power to one motor to perform only the basic function of sucking dust and foreign substances are inserted, and the water washing function is performed together with the basic function of sucking dust and foreign substances. Another motor, ie, two motors, is divided into two types that insert four wires that each supply power.

1 to 8 illustrate a conventional vacuum cleaner hose by way of example.

First, FIG. 1 is a perspective view illustrating a state in which a target material 2 into which two electric wires 5 are inserted is wound in a spiral manner and molded into a hose.

In addition, the target material 2 for forming the hose 1 is, as illustrated in various forms in Figures 2, 3, 4, 5, the one hooked shape of the raised shape (3), along with the constant It is composed of two to four hollow protrusions (4) that are spaced apart at each interval, and each of the hollow protrusions (4) inside the one or two strands of wire (5) is inserted into the hook ( It is integrated in the state connected with each other by the cover 3a of the shape similar to 3).

That is, in FIG. 2, two wires 5 are inserted into two hollow protrusions 4 one by one, and in FIG. 3, four wires 5 are respectively inserted into four hollow protrusions 4. Two hollow protrusions 4 inserted into one strand and inserted into each of the two hollow protrusions 4 and the two wires 5 inserted together, as shown in FIG. It consists of a form.

In FIG. 5, four wires 5 are divided into two hollow protrusions 4 and inserted into two strands, respectively.

Accordingly, as shown in the drawings, the conventional vacuum cleaner hose is the result of inserting all the wires 5 in every hollow protrusion 4 wound over the entire length, which is a function of the wires 5. In view of the limitation of power transmission to the motor, the insertion length of the wire was longer than necessary, which was a wasteful factor.

In addition, since the wire 5 is made of expensive copper wire as its material, the longer the length of use of the wire 5, the higher the production cost of the product. For the first time, the hose was economically inefficient, and as the amount of wire used increased, the unit weight of the hose was relatively increased, which was disadvantageous in transportation and handling.

The present invention solves the problem that the use length of the wire in the conventional vacuum cleaner hose as described above was inevitably longer than necessary to significantly reduce the wire usage, significantly reducing the production cost of the hose and at the same time light weight and flexible vacuum cleaner The purpose is to provide a hose.

In the present invention for achieving the object as described above, in forming a vacuum cleaner hose (1) by winding a spiral wound the target material (2) integrally side by side several hollow protrusions,
The hose 1 is formed by continuously winding a single line of the target material 2 separated by the hollow protrusion 4 into which the wire 5 is inserted and the hollow protrusion 4a into which the wire 5 is not inserted. And
