Behavior pattern-based intelligent cooker dry-burning-resistant device

Abstract

The invention relates to a behavior pattern-based intelligent cooker dry-burning-resistant device. The behavior pattern-based intelligent cooker dry-burning-resistant device comprises a controller, adiffusion reflection photoelectric switch, an infrared sensor, a motor, a gear and a bearing, wherein the diffusion reflection photoelectric switch and the infrared sensor are connected with the controller; the motor is controlled by the controller; the gear is driven by the motor; the bearing is arranged outside a gas cooker rotary knob in a sleeving way; the bearing is provided with a pedestal fixed with the cooker surface and a rotatable part arranged on the pedestal; a stirring head is fixed in the zero point position of the rotary knob; teeth engaged with the gear are arranged on the outer edge of the rotatable part; the rotatable part is provided with a first stop block which is matched with the stirring head and used for enabling the rotary knob to rotate clockwise; in an initial state, the first stop block is positioned on the right side of the six o'clock position of the rotary knob; and the diffusion reflection photoelectric switch and the infrared sensor are arranged at themiddle part of one side, near people, of a cooking bench. When people normally use the cooking bench, the control device does not generate resistance on the rotary knob; the control device can controlthe rotary knob well when control is needed; and when people depart from the cooking bench, the fire can be turned off automatically.

Description

technical field [0001] The invention relates to a behavior mode-based dry-burn prevention device for an intelligent cooker. Background technique [0002] In the 21st century, my country has initially entered the era of informationization and intelligence. With the development of science and technology, people's requirements for intelligent life are increasing day by day. In recent years, the concept of smart home has gradually penetrated into people's lives and is constantly affecting people. The kitchen is a place where people cook, and it is closely related to people's diet and life. A few years ago, Haier launched an anti-dry-burning gas stove, which uses a "patented anti-dry-burning temperature sensor" to detect the temperature of the bottom of the pot, so as to prevent dry-burning. However, improvements are still needed for the transformation of existing gas stoves and the misjudgment rate of the judgment mechanism. [0003] After searching, it is found that Chinese ...

Problems solved by technology

It can turn off the gas stove at regular intervals, but the degree of intelligence is too low, and it will be turned off during normal use, which is very inconvenient. Moreover, gear A and gear B are always in a meshing state, and there is also a large resistance to turning the knob, which makes the user experience difficult. bad question

[0005] The above several inventive devices all need to transform the existing cooker, and the user needs to replace the cooker when using
