Embodiment Construction

[0037] Going back to these drawings, in figure 1 The microwave oven transformer 10 includes: a first iron core 11 , a second coil 12 , a heating coil 13 , a magnetic circuit iron core 14 , a first coil 15 and a second iron core 16 .

[0038] The first iron core 11 includes a plurality of E-shaped iron pieces. At the center portion of the first core 11, the second coil 12 and the heating coil 13, and the first coil 15 are provided with the magnetic circuit core 14 embedded therebetween. The second iron core 16 includes a plurality of I-shaped iron pieces welded to each other, and is welded to the lower portion of the first iron core 11 . A bracket 17 is welded to the underside of the second core 16 for assembling the transformer 10 to the equipment room of the microwave oven.

[0039] In the transformer 10 for microwave ovens, when a universal voltage (commercial power) is applied to the first coil 15, a certain voltage is applied according to the turns ratio between the firs...

Abstract

A transformer for a microwave oven capable of preventing its quality from being degraded due to damage to insulating paper, comprising: a first core having a coil inserting portion having an open side; a plurality of coils are sequentially inserted into the coil inserting in a state of being electrically insulated from each other a portion; a second core combined with the first core for covering an opening side of the coil embedding portion; an auxiliary spacer portion having a plurality of holes formed on its outer surface and having a plurality of coils sequentially embedded therein; And a resin molded portion completely covering the outer surfaces of the plurality of coils and the auxiliary spacer portion.

Description

technical field [0001] The present invention relates to a transformer for microwave ovens, and more particularly, to a transformer for microwave ovens having an improved coil insulation structure. Background technique [0002] Generally speaking, a transformer for microwave ovens receives a common voltage and outputs a high voltage for driving a magnetron. A magnetron is an electron tube in which the flow of electrons from a cathode to one or more anodes is controlled by an applied magnetic field. Magnetrons are used to generate alternating current at microwave frequencies. Magnetrons are used in microwave ovens to generate microwaves in cooking food. [0003] A transformer is an electrical device that, through electromagnetic induction, transforms the electrical energy of one or more circuits into the electrical energy of one or more other circuits of the same frequency but usually of different voltage and current values. The transformer includes at least two coils. A t...
