Relay switch

Abstract

The present invention relates to a relay switch for a bread toaster, comprising an outer case, a first conductive end and a second conductive end that are electrically connected with an outer power supply and that are arranged on the outer case, an electromagnetic coil that is positioned at the bottom of the outer case, an armature iron that is arranged on a relay switch and matched with the electromagnetic coil, a connection mechanism that is connected electrically with the second conductive end and matched separably with the first conductive end, a transmission mechanism that is movably connected with the armature iron, and a reposition mechanism; wherein, the electrical link between the connection mechanism and the first conductive end can be cut off by the reposition mechanism after the electromagnetic coil has electricity, thus making the bracket of the bread toaster locked or springing not enough but cutting off the external power supply when the timer normally works.

Description

【Technical field】 [0001] This invention relates to electric heating devices, and more particularly to relay switches for toaster ovens. 【Background technique】 [0002] The electronic toaster oven in the prior art is generally composed of parts such as a shell, a lapel, a base, an electronic timer, and a movement. Its main functions include timing and external reset. Adjust the time as needed, so that the color of the baked bread slices meets the user's preference. Its working process is as follows: Usually, after the user inserts the power plug of the toaster oven into the power socket, put the bread into the bread slot of the toaster oven, the slider and the bracket connected by the lapel hold the bread, and adjust the knob to set the electronic timer. When the desired baking time is reached, press the handle, the carriage and the bracket will lower the bread to the bottom of the tank. At this time, because the switch is powered on, the coil on the electronic timer is ener...

AI Technical Summary

Problems solved by technology

However, due to various accidents or some defects of the toaster oven itself, the toaster oven bracket is stuck due to bread or other reasons or does not bounce up in place, the time set by the timer is reached, the coil loses power, and the armature loses suction. However, the bracket still cannot bounce back to its original position, so that the power switch of the toaster oven cannot be disconnected, causing the heating wire in the toaster oven to be energized for a long time, and the bread is toasted until the bread is burnt or burnt, and even accidents occur

[0003] In addition, the current toaster power switch, the placement of the armature and the coil are generally open or unprotected, and the arc light generated when the switch is closed and disconnected can be seen outside the toaster oven, which easily leads to product returns; The power switch and armature will not work properly due to breadcrumbs and other dust
