Description

Non-glue close-wound coil panel

Technical Field

The invention relates to an induction cooker coil panel, in particular to a glue-free close-wound coil panel.

Background

At present, a plurality of wire winding parts are generally arranged on a coil panel support of an existing induction cooker, enameled wires are wound on the front faces of the wire winding parts, magnetic stripes are arranged on the back faces of the wire winding parts, and coils wound by the enameled wires and the magnetic stripes are respectively positioned on two sides of the coil panel support. When the coil panel is used for fixing the enameled wire, the enameled wire is usually required to be adhered to the coil panel bracket by using an adhesive, however, when the coil panel is adhered by using the adhesive, if the coil panel is in a high-temperature condition for a long time, the adhered part of the adhesive is easy to age, and the coil is separated from the coil panel bracket.

Therefore, there is a need for an improved coil panel for an induction cooker.

Disclosure of Invention

The invention aims to provide a coil panel which is convenient to assemble and can fix a coil without adhesive.

In order to achieve the purpose, the invention adopts the following technical scheme:

a non-glue close-wound coil panel comprises a coil panel bracket, a coil and a plurality of magnetic strips, and particularly, the coil panel bracket comprises a base, a top cover and a winding post for connecting the base and the top cover; a winding space is formed between the base and the top cover; the coil is positioned in the winding space and wound on the winding post; the base is also provided with a plurality of magnetic stripe mounting grooves; the magnetic strip is arranged in the magnetic strip mounting groove.

The principle of the invention is as follows:

the coil is wound on the winding post in a close winding mode. The position of the coil can be limited by the winding space formed between the base and the top cover, the coil can be wound in the winding space, and the base and the top cover can compress the coil, so that the coil is shaped without using a binder, and is also bonded with the coil panel support without using the binder, and the fixed molding can be realized.

Compared with the existing surface coil installation process, the coil panel can realize the fixation of the coil without additionally using other equipment and auxiliary materials (such as adhesive, baking equipment, hot-pressing equipment and the like). In addition, the coil is not adhered or thermally welded with the coil panel into a whole, but is limited by the base and the top cover and is pressed tightly, so that the coil can still be detached from the coil panel.

Since the induction cooker has a small volume and is mostly flat, the bottom plate is preferably plate-shaped, and the top cover is preferably plate-shaped. The bottom plate and the top cover are parallel to each other, and the winding posts are perpendicular to the bottom plate, so that coils wound in the winding space are guaranteed to be neat and compact.

Except that base and top cap compress tightly the coil, in above-mentioned coil panel, can be equipped with the first magnetic stripe mounting hole of a plurality of on the wrapping post, the outside of top cap can be equipped with a plurality of second magnetic stripe mounting hole, and this first magnetic stripe mounting hole and second magnetic stripe mounting hole all are linked together with the magnetic stripe mounting groove. The magnetic stripe is installed in the magnetic stripe mounting groove that corresponds and is embedded in corresponding first magnetic stripe mounting hole and the second magnetic stripe mounting hole that corresponds to make the outside of coil surround by each magnetic stripe, but magnetic stripe and coil contactless. The outside of the top cover means an area close to the edge of the top cover and not covering the coil.

In order to ensure the heat dissipation effect of the coil panel, a plurality of heat dissipation holes can be arranged on the base and the top cover so as to prevent heat dissipated by the coil closely wound on the winding post from accumulating in the winding space when the coil works.

The coil panel can also comprise a plurality of gland covers in annular structures for winding the upper coil with a multi-ring structure; the pressing covers surround in sequence, and the pressing cover closest to the top cover surrounds the top cover; the gland is provided with a winding stop block connected with the base, and the winding stop block is arranged around the central axis of the gland; the winding block is also provided with a lead through hole for leading in the coil; a secondary winding space is formed between the gland and the base; the coil is positioned in the secondary winding space and is wound on the winding stop block.

The pressing covers sequentially surround the two adjacent pressing covers, and the pressing cover close to the winding post is positioned in the pressing cover far away from the winding post and is surrounded by the pressing cover far away from the winding post.

Due to structural limitations of the induction cooker, the gland is preferably of a plate-like structure. And in order to ensure that the coil wound in the secondary winding space is neat and tight, each gland is level with the top cover.

In order to simplify the assembly of the gland and the base, a plurality of buckling blocks can be arranged on the winding stop block, and a plurality of buckling block through holes matched with the buckling blocks are arranged on the base. The fastening blocks are fastened into the corresponding fastening block through holes, and the assembly of the gland and the base can be completed quickly.

If be equipped with the gland in this coil panel, set up originally and then set up on the gland in the top cap outside and lie in the outside of this gland in the second magnetic stripe mounting hole of top cap outside, set up and still be linked together with the magnetic stripe mounting groove that corresponds in the second magnetic stripe mounting hole of the gland in the outside. The outermost gland is the gland furthest from the top cover.

In order to ensure the heat dissipation effect of the coil panel, each press cover can be provided with a plurality of heat dissipation holes so as to prevent heat dissipated by the coil tightly wound on the winding post from accumulating in the secondary winding space when the coil works.

The invention has the advantages of convenient assembly, no need of using adhesive for the coil, no additional assembly process for the coil and the coil panel bracket, and the like.
