Abstract
Description
Technical Field
[0001] This utility model relates to the field of induction cooker technology, specifically to a coil structure for an induction cooker. Background Technology
[0002] Currently, induction cookers consist of a crystal plate, a coil, and a coil spool. The coil is installed inside the coil spool, and the crystal plate is placed directly above the coil. When the crystal plate breaks, water from it will drip directly onto the coil and coil spool, causing short circuits and damage to the induction cooker's components, and even posing a risk of electric shock. Utility Model Content
[0003] The purpose of this invention is to provide a coil structure for induction cookers that is safer than existing technologies.
[0004] The purpose of this utility model is achieved as follows.
[0005] A coil structure for an induction cooker includes a coil and a tray. The center area of the tray is recessed to form a first cavity, and the center area of the coil is recessed to form a second cavity. The coil outline edge is provided with positioning ears, and the positioning ears are provided with positioning grooves. The tray is provided with a positioning bracket. The tray sits on the coil, and the positioning bracket is inserted into the positioning groove. The first cavity is placed in the second cavity, and a coil receiving cavity is formed between the first cavity and the second cavity.
[0006] Furthermore, the positioning bracket is provided with a first connecting hole, and the bottom surface of the positioning groove is provided with a second connecting hole. The first and second connecting holes are aligned vertically. The positioning bracket and the positioning ear are connected and fixed by bolts and nuts passing through the first and second connecting holes. The bolts and nuts restrict the vertical displacement of the coil and tray, making the installation more secure.
[0007] Furthermore, the positioning ear includes two first ears and two second ears, the two first ears are symmetrically arranged between each other, the two second ears are symmetrically arranged between each other, the two first ears are spaced apart by the second ears, and the included angle between adjacent first ears and second ears is not 90°. The positioning bracket includes two first brackets and two second brackets, the two first brackets are symmetrically arranged between each other, the two second brackets are spaced apart by the second brackets, and the included angle between adjacent first brackets and second brackets is not 90°. The first bracket is inserted into the positioning groove of the first ear, and the second bracket is inserted into the positioning groove of the second ear.
[0008] Foolproof assembly of coils and trays.
[0009] Furthermore, the coil has an annular support portion outside the second concave cavity, and the positioning ear portion is located on the outer side of the annular support portion. The tray has an annular protrusion outside the first concave cavity, and the positioning bracket is located on the outer side of the annular protrusion portion. The annular protrusion portion sits on the annular support portion. This restricts the vertical displacement of the tray and avoids damage to the coil.
[0010] Furthermore, the top surface of the annular support is provided with an annular groove, and the bottom of the annular flange is provided with an annular protrusion. The bottom surface of the annular flange and the top surface of the annular support abut against each other, and the annular protrusion is inserted into the annular groove. The coil and tray are not easily displaced radially.
[0011] Furthermore, the second cavity is provided with several heat dissipation perforated areas. The coil dissipates heat downwards through these perforated areas, preventing heat accumulation from affecting the normal operation of the induction cooker.
[0012] Furthermore, the coil is provided with a bottom ring and a middle ring. The annular support, middle ring, and bottom ring are arranged from high to low, and their centers are on the same axis. The annular support, middle ring, and bottom ring are connected and fixed by a number of first arc-shaped parts, which are arranged in annular equidistant intervals. The annular support and middle ring are connected and fixed by a number of second arc-shaped parts, which are arranged in annular equidistant intervals. The second arc-shaped parts are located between two adjacent first arc-shaped parts. The space between the annular support, middle ring, bottom ring, first arc-shaped parts, and second arc-shaped parts constitutes the heat dissipation hollow area.
[0013] The heat dissipation perforation area is easy to form, which improves the heat dissipation effect of the coil.
[0014] Furthermore, the top surfaces of the middle ring, bottom ring, first arc-shaped portion, and second arc-shaped portion are provided with annular coil mounting positions, and the annular support portion is provided with mounting grooves, the bottom of which is lower than the bottom surface of the annular groove.
[0015] The coil is easy to install, and the mounting slot facilitates wiring.
[0016] Furthermore, the first cavity is provided with a clearance hole in the middle, and the first cavity is provided with an annular wall around the clearance hole.
[0017] The clearance hole facilitates wiring, and the annular wall prevents water from dripping onto the coil through the clearance hole.
[0018] Furthermore, the bottom of the tray is provided with an annular support portion. The bottom surface of the tray, the annular convex edge, and the annular support portion are connected by reinforcing ribs. The second concave cavity has an abutment portion corresponding to the annular support portion. The abutment portion supports the bottom of the first concave cavity through the annular support portion. The first concave cavity has a fixing slot corresponding to the reinforcing rib, and the reinforcing rib is inserted into the fixing slot. The tray is less prone to deformation and compression of the coil, improving the safety of use.
[0019] This invention uses a tray placed above the coil to prevent water from dripping directly onto the coil after the crystal plate breaks, thus preventing short circuit damage to components and the risk of electric shock. Compared with existing technologies, it is safer to use. Attached Figure Description
