Range hood

Abstract

The invention provides a range hood. The range hood comprises a body, a first central control unit, a control panel, more than one induction electrode, a capacitance induction chip, a second central control unit and a communication unit. One or more induction electrodes are arranged on the induction area of the control panel, the one or more induction electrodes sense capacitance data between electrodes and a human body, the capacitance induction chip is electrically connected with the one or more induction electrodes, the capacitance induction chip collects one or more capacitance value data,the second central control unit is electrically connected with the capacitance induction chip, the second central control unit receives one or more capacitance value data sent by the capacitance induction chip and compares the one or more capacitance value data with a preset threshold value. The communication unit is electrically connected between the first central control unit and the second central control unit, and receives a first command output by the second central control unit and sends a second command to the first central control unit. The range hood has the advantages of good maneuverability and sensitive control.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood. Background technique [0002] With the gradual intelligence of electronic devices, it brings more and more convenience and fun to people. Common intelligent electronic devices include smart phones and tablet computers with touch screens. The development of intelligent electronic equipment has also gradually brought positive impacts on household appliances and kitchen appliances, making household appliances and kitchen appliances gradually develop towards intelligence. [0003] At present, there are more and more types of smart kitchen appliances, such as rice cookers, cooking machines, range hoods, etc. Among them, some of the existing range hoods can have touch and gesture control functions, and the above-mentioned touch and gesture control is mainly based on infrared sensing equipment, which is mainly through each button in the button area of ​​the ran...

AI Technical Summary

Problems solved by technology

[0004] However, the infrared signals emitted by the existing infrared probes are all pointing signals in a specific direction, which leads to the fact that the normal realization of the infrared probe is closely related to factors such as individual differences such as the user's gestures, which in turn makes the infrared probe prone to misjudgment and Case of miscarriage of justice

In addition, due to the directional nature of infrared rays, the installation of the infrared probe requires opening holes in the button panel area, and it is necessary and guaranteed that the openings are located in strict alignment with the emitting and receiving areas of the infrared probe, resulting in the design and installation of the range hood. High standard

In addition, the infrared rays emitted by the infrared probe are easily absorbed and blocked by oil, water, dust-covered glass panels and other media, resulting in the failure of the gesture control function of the range hood.
