Linking system for extractor hood and kitchen range and linked communication method

Abstract

The invention relates to a linking system for an extractor hood and a kitchen range and a linked communication method. The kitchen range and the extractor hood are equipped with infrared transceiver devices and radio-frequency transceiver devices, treatment measures of tightly arranging an infrared emitting device and an infrared receiving device in each infrared transceiver device and isolating through a light path are taken, so that a signal interference problem while the kitchen range or the extractor hood emits an infrared signal is avoided; moreover, the controllable characteristic of theinfrared signal direction is further utilized to timely prompt that the infrared signal is shielded; a combined communication way of infrared communication and radio-frequency communication is adopted, so that communication connection between the kitchen range and the extractor hood is further matched by utilizing radio-frequency communication after the kitchen range and the extractor hood establish infrared communication connection, and therefore, radio-frequency communication matching errors are avoided. A linking processor in the kitchen range can timely switch between a primary communication way and a secondary communication way between infrared communication and radio-frequency communication according to a communication success or failure condition, so that communication quality andstability during linkage of the extractor hood and the kitchen range is guaranteed.

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...

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 to be linked, and there is a problem of easy matching errors; As a result, there is a risk of signal interference between the cooker and range hood and the signal is shielded by metal, making it difficult to ensure the stability of the range hood linkage.
