Abstract

(57) [Summary] [Purpose] To reduce the assembly time of the coil unit. [Structure] Non-metallic coil base 1 and this coil base 1
Ritzsen 2 to be wound around and attached to the coil base 1 and ferrite 3 to be attached to the opposite side of the coil base 1 from the Ritzsen 2 attachment surface
In the coil unit having the above, a through hole 7 that penetrates to the winding side of the Litzsen 2 is provided at a position where the ferrite 3 is attached to the coil base 1, and the adhesive 4 is provided in the through hole 7.
Is a coil unit in which the wound Litzsen 2 is fixed at the same time that the ferrite 3 is bonded and the ferrite 3 is bonded. [Effect] At the same time as the ferrite is attached, the wound Litzsen can be fixed, and the assembly time of the coil unit can be shortened.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coil unit of an electromagnetic induction heater.

[0002]

[Prior art]

 A conventional coil unit is, for example, as shown in Japanese Utility Model Publication No. 63-4394, after the adhesive is filled from the upper surface of the Ritzsen wound around the coil base and the adhesive is dried and fixed. The ferrite was attached to the back side with an adhesive.

[0003]

[Problems to be solved by the device]

 In the conventional technology, as described above, the adhesive is filled from the upper surface of the Ritz sen wound around the coil base and dried and fixed, and then the ferrite is attached to the adhesive with the Ritz sen installation surface on the back side. It took a long time to assemble the coil unit.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and has a coil unit having a non-metallic coil base, a Litzsen wound around a coil base and mounted, and a ferrite mounted on the opposite side of the coil base from the Ritzsen mounting surface. In the above, the coil base is provided with a hole that penetrates to the winding side of the Ritzsen, and the through hole is filled with an adhesive to bond the ferrite, and at the same time, the wound Ritzsen can be bonded and fixed.

[0005]

[Action]

 With the above configuration, the wound Litzsen and ferrite can be bonded at the same time, and the coil unit assembly time can be shortened.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a coil unit according to an embodiment, and FIG. 2 is a bottom view of the same.

In the figure, 1 is a non-metal coil base, 2 is a Litzsen made by combining a plurality of small-diameter copper wires whose surfaces are insulation-coated, 3 is a ferrite, and 4 is an adhesive material.

The structure is such that a cylindrical projection 8 is provided in the center of the coil base 1 so that the Ritz sen 2 can be wound, and a small hole 5 through which the Ritz sen 2 passes is provided in the vicinity thereof, and one end of the Ritz sen 2 is passed through the small hole 5 and its position Is wound in a plane spiral shape and the outer peripheral edge is fixed to the coil base 1 by a stopper 6. A plurality of ferrites 3 are arranged on the back side of the coil base 1. Further, the through hole 7 of the coil base 1 is filled with the adhesive 4 in order to fix the wound Litzsen 2 and to attach the ferrite 3.

Next, the operation of this embodiment will be described. The adhesive used here is filled with heat-resistant material, and it takes a day and night to attach and fix the Ritzsen 2 and adhere the ferrite 3, but since the fixing is completed once, the assembly time The workability is improved to 1/2 that of the conventional one.

[0010]

[Effect of device]

 As described above, according to the present invention, the ferrite mounting position of the coil base has a hole penetrating to the winding side of the Ritzsen so that the wound Litzsen can be fixed at the same time when the ferrite is mounted, and the coil unit assembly time can be shortened. Can be planned.
