Starting mechanism of toaster

Abstract

The invention discloses a starting mechanism of a toaster and relates to a bread recognition and starting mechanism of a toaster. The starting mechanism comprises a rack (9), a sliding frame (1) which can move up and down, a control circuit and a sensing device (401) which is used for identifying the angular displacement of a support (502), wherein the rack (9), the sliding frame (1) and the control circuit are arranged inside a casing, the sliding frame (1) is connected with a bracket (5), the support (502) is fixed at one end of the bracket (5), the support (502) on the bracket (5) is hinged with the sliding frame (1), a light barrier (501) is arranged on the support (502), the sensing device (401) is arranged on a moving track of the light barrier (501), the light barrier (501) can shield a sensing light passage of the sensing device (401), and the sensing device (401) is connected with the control circuit through a data line. According to the starting mechanism, the bracket is rotated by a certain angle upwards with a hinging point serving as a circle center by the aid of the elastic force of a spring, the bracket returns to the original position when bread is placed in the toaster, the sensing device obtains signals for returning of the bracket and transmits the signals to a control chip to control the toaster to start automatically, and the starting mechanism has the advantages of being simple in structure, safe, reliable and low in cost.

Description

technical field [0001] The invention relates to a toaster, in particular to a bread identification and starting mechanism of the toaster. Background technique [0002] The electronic toasters sold in the market are generally manually pressed down, and the carriage and the bracket connected to the carriage support the bread and drop to the bottom of the slot. At this time, the switch is powered on, and the coil on the electronic timer is energized. , the armature is sucked, the switch is kept on, the flap, slide and bracket are kept in place, the heating wire starts to work, and the bread is baked. When the baking time reaches the time set by the electronic timer, the electronic The coil on the timer is de-energized, the armature is loose, and the carriage, lapel and bracket are supported by the tension of the extension spring to hold up the bread spring to a normal position. The disadvantages of this toaster structure are: the bounce force of the bracket tension spring is t...

AI Technical Summary

Problems solved by technology

The disadvantages of this toaster structure are: the bounce force of the bracket tension spring is too large, and the small bread will be bounced; the bounce force of the bracket tension spring is too small, and the large bread cannot bounce up; The height is not high enough to take out the bread

Furthermore, people use a motor to drive the lifting of the sliding frame of the automatic toaster to realize the automatic lifting of the sliding frame. However, the use of this structure has the disadvantage that the motor needs to be manually started, and the toaster cannot automatically identify whether to put bread.
