Linkage system and linkage communication method for range hood and kitchen range

Abstract

The invention relates to a linkage system and linkage communication method for a range hood and a kitchen range. The kitchen range adopts a plurality of groups of infrared receiving and transmitting devices to communicate with a group of infrared receiving and transmitting devices in the range hood, and corresponding default transmitting priorities are set for each group of infrared transmitting devices in the kitchen range, so that each group of infrared transmitting devices in the kitchen range sequentially transmits data to the range hood according to the sequence of the default transmitting priorities, therefore, the direction of infrared signals emitted by the kitchen range is controllable, and as long as one group of infrared receiving devices successfully receives response signals of the range hood, data transmission of other groups of infrared emitting devices is stopped, and linkage communication between the kitchen range and the range hood is established, so that the problemthat the infrared transmitting and receiving devices are shielded is effectively solved, signal interference caused by data emitted by different groups of infrared emitting devices of the kitchen range is avoided, mutual interference among the signals is reduced, and therefore, the stability between the kitchen range and the range hood is ensured during linkage communication.

Description

technical field [0001] The invention relates to the field of intelligent kitchen appliances, in particular to a linkage system and linkage communication method of a range hood and a cooker. Background technique [0002] With the advancement of science and technology, kitchen appliances are becoming more and more intelligent. In order to meet the needs of simplifying user operations, different kitchen appliance manufacturers have successively proposed more and more smoke stove linkage schemes. [0003] The existing range hood linkage scheme proposed by various kitchen appliance manufacturers mainly achieves the linkage control effect between the range hood and range hood by installing different devices. Specifically, by installing a cooker switch and a temperature detection device on the cooker to ensure that the state of the cooker can be accurately judged, and then installing devices such as RF modules and Bluetooth modules that can realize data transmission between the co...

AI Technical Summary

Problems solved by technology

[0004] However, there are still some shortcomings in the above-mentioned existing smoke cooker linkage scheme: due to the use of wireless communication devices such as RF modules, Bluetooth modules or WIFI modules that transmit radio frequency signals, the radio frequency signals emitted by such wireless communication devices have With large coverage and strong wall-penetrating ability, the cooker and range hood need to be matched before they can be linked together, and there is a problem of matching errors; The signals between the stove and range hood interfere with each other and there is a risk of the signal being shielded by metal, which makes it difficult to guarantee the stability of the range hood linkage
