Adjusting device for door opening speed of cooking equipment with automatic opening structure

Abstract

The present invention provides a lever (300). The lever (300) opens a door (720) by pushing a latch (200), which is inserted into a support latch holder (10) and latched, in an opening direction of the door (720) to release the latching. And the lever (300) is automatically controlled by a control part (90). According to an automatic door opening mechanism, when power is supplied to the cooking device or a power supply of the cooking device is turned on by a user, control for aligning the lever (300), the pushing member (500) and the pushing member driving part (600) to a fixed position is executed. Furthermore, after a user inputs a door opening command, in order to perform a door opening operation, it is possible to check whether or not each component related to an automatic door openingoperation is abnormal by means of a change in a recovery / stop switch and a change in an opening detection switch that occur when the motor is rotated one turn. When the latch is unlocked, the door, the initial opening angle of which has been opened, is automatically opened by self-weight pull-down, and from a predetermined opening angle, the door can be slowly moved downward and opened by means of the intervention of the damper (the controlled speed).

Description

technical field [0001] The invention relates to a cooking device using an automatic opening structure to automatically open the door, a method for controlling the action of the door of the cooking device, and a device for controlling the opening speed of the door. Background technique [0002] Cooking equipment such as an oven or an electromagnetic microwave oven has a cuboid-shaped appearance as a whole, and the inner cooking chamber is in the form of opening to the front, and a door is arranged in front of the cooking chamber. [0003] Doors can be opened in various ways, but the most widely used method is mainly that hinged doors are opened and closed by turning around the axis of rotation. Most of these types of doors are provided with a handle or groove for the user to grasp. [0004] Recently, a function to automatically open and close the door of the cooking device is being added. However, there is a problem in the way of automatically opening the door realized by t...

AI Technical Summary

Problems solved by technology

However, there is a problem in the way of automatically opening the door realized by the cooking equipment in the prior art, since it is necessary to overcome the elastic force applied to the door for increasing the closing force of the door to open the door, correspondingly, it is necessary to Use a drive unit with high output power

On the contrary, if the damping force is reduced to increase the initial opening speed, as the opening angle of the door increases, the opening force will also become larger, thereby exceeding the damping force, so there is a problem that the door will be opened suddenly
