Bread toaster with safe lock

Abstract

The invention discloses a bread toaster with a safe lock. The bread toaster comprises an oven, a bread stand, a pressing part, an electromagnetic switch device and a power supply circuit; the pressing part is provided with a touch-pressing block and a clamping hook part; the electromagnetic switch device comprises a switch seat, an electromagnet device, an electromagnetic switch block and power switches, the electromagnetic switch block is provided with a touch-pressing surface and a clamping hook position, when the pressing part moves downwards, the touch-pressing block presses against the touch-pressing surface to drive the electromagnetic switch block to turn over downwards to trigger the power switch to be switched on, the electromagnet device adsorbs the electromagnetic switch block to keep the circuit communicated, and the bread stand is kept in the oven through the clamping hook structure; when a control device disconnects a power supply of the electromagnet device, the electromagnetic switch block turns over upwards, the clamping hook part slides out of the side face of the clamping hook position, and the bread stand is reset; when the bread stand or the pressing part is clamped, after the electromagnet device is powered off, the electromagnetic switch block is released to turn over upwards to separate from the power switch, therefore, disconnection of the power supply circuit is guaranteed, a heating unit does not conduct heating any more, potential safety hazards are eliminated, and the safety is higher.

Description

technical field [0001] The invention relates to a toaster, in particular to a toaster with a safety lock. Background technique [0002] Current toasters usually use electromagnetic switches. During the baking operation, the bread frame moves down through the pressing component to trigger the switch device, the electromagnet coil and the heating unit supply power, and the electromagnet absorbs the pressing component to keep the circuit conducting. After the set baking time, the time controller cuts off the power supply of the electromagnet coil, and the pressing component is not absorbed. Under normal circumstances, the pressing component and the bread rack will automatically rise and reset under the action of the spring, but if the pressing component or the bread rack is due to When factors such as mechanical rust and foreign matter get stuck, the heating unit will continue to be powered on and heated, causing the bread to be scorched or even a fire hazard, which poses a cer...
