A control method and device for linkage between a smoke and a range

By adjusting the suction power of the air vent according to the weight and position of the pot before the stove is ignited, the problem of the range hood not being able to suck in the initial stage of oil fumes in the existing range hood and stove linkage system is solved, resulting in better smoke extraction and user experience.

AI Technical Summary

Technical Problem

In existing range hood and stove linkage systems, the range hood cannot promptly draw in the initial stage of cooking fumes after the stove is ignited and before it starts operating, resulting in poor smoke extraction.

Method used

Before cooking, the range hood is activated based on the weight of the cookware. The suction power of the vent is adjusted based on the weight and position of the cookware before the stove is ignited to ensure that the range hood can promptly draw in the initial fumes. This includes determining the target burner based on the weight of the cookware and adjusting the suction power of the vent before the stove is ignited.

Benefits of technology

It effectively prevents the spread of cooking fumes, improves smoke extraction efficiency, and enhances user experience and safety.

Abstract

This invention relates to the field of intelligent home appliance control technology, specifically a control method and device for the linkage between the range hood and the cooktop. The method includes obtaining the weight of the pot on any burner of the cooktop and the initial weight of the pot; if the weight of the pot is greater than a first preset weight, identifying the burner with the pot weight greater than the first preset weight as the target burner, and determining the location information of the target burner; controlling two air intakes to operate at a first preset suction power; if a user start command is received for the target burner, determining the target air intake corresponding to it based on the location information; controlling the target air intake to increase its suction power from the first preset suction power to a second preset suction power, and controlling the other air intake to increase its suction power from the first preset suction power to a third preset suction power; this invention activates the range hood based on the weight of the pot before cooking begins, ensuring that the range hood can draw in the initial fumes generated by the cooktop, preventing fumes from escaping and improving the smoke extraction effect.
