Structure of time meter for electric appliance

Abstract

Provided is a structure of a time meter for an electric appliance. The structure of the time meter for the electric appliance comprises a rotary knob, a timer and a mounting plate, wherein the timer is fixed on the mounting plate, a connecting shaft of the timer runs through a hole of the mounting plate and fixedly connected with the rotary knob, the rotary knob is provided with a button, the rotary knob and the button are cooperatively provided with a resetting spring, and a limiting assembly is arranged among the rotary knob, the button and the timer; when the button is not pressed, the button is limitedly matched with the limiting assembly, and thereby the rotary knob is limited to be screwed in a long-pass gear; when the button is pressed, the button and the limiting assembly mutuallyremove the limiting, and thereby the rotary knob is screwed in the long-pass gear; the limiting assembly comprises a connecting rod and a sliding block; the button is a hollow cylinder, the end face where the button and the resetting spring generate the elastic action is provided with a via hole in matched connection with the connecting rod, and the periphery of the via hole is provided with flanges. The structure of the time meter for the electric appliance has the advantages that the structure is simple and reasonable, the performance is excellent, the disassembly and the assembly are quick,the operation is convenient, the manufacture cost is low, and the structure of the time meter for the electric appliance is safe and reliable, and the structure of the time meter for the electric appliance is widely applied to other appliances with long-pass timing functions.

Description

technical field [0001] The invention relates to a structure of a timer for electrical appliances, in particular to a structure for a timer for electrical appliances with long-pass timing function. Background technique [0002] An electric oven is a frequently used kitchen appliance. It uses the radiant heat emitted by the electric heating element to bake food. It can be used to process some pasta, such as bread and pizza, and can also be used to make desserts such as egg tarts or small biscuits. It is very easy to use. convenient. During use, the baking time needs to be controlled in order to produce satisfactory food. Therefore, the existing electric ovens are all designed with a timer function, and correspondingly equipped with a timer knob, so that users can adjust and operate the timing function of the timer conveniently. As the Chinese patent publication number is the electric oven mentioned in CN201743526U, the timer is a mechanical timer. One end of the main body o...

AI Technical Summary

Problems solved by technology

Since the long-pass position is to keep the electric oven in the baking state continuously, in some safety regulations, it is not allowed to switch to the long-pass position so easily, which will lead to safety accidents due to user misoperation
