Abstract

The invention discloses a kitchen device. The kitchen device comprises an oil fume detection assembly, wherein the oil fume detection assembly comprises a light emitting device and a light receiving device, the light emitting device comprises an emitting part and a first sealing plug, a first inner cavity is formed in the first sealing plug, the emitting part is at least partly located in the first inner cavity, a first oil guiding groove is formed in the inner wall of the first inner cavity, the light receiving device comprises a receiving part and a second sealing plug, a second inner cavityis formed in the second sealing plug, the receiving part is at least partly located in the second inner cavity, a second oil guiding groove is formed in the inner wall of the second inner cavity, andthe open direction of the first oil guiding groove and the open direction of the second oil guiding groove are in an at least partly stagger state. In the kitchen device, the open direction of the first oil guiding groove and the open direction of the second oil guiding groove are in the at least partly stagger state, interference from stray light reflected by the oil guiding grooves to the lightreceiving device can be reduced, and sensitivity of the light receiving device is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of kitchen appliances, and more specifically, to a kitchen device. Background technique [0002] In the related art, the oil suction device has an optical sensor to detect the concentration of oil fume, and the air volume of the fan of the oil suction device is controlled according to the detected concentration of oil fume. Specifically, the photosensor includes a phototransmitter and a photoreceiver. The phototransmitter emits light into the oil fume duct of the oil suction device, and the photoreceiver is used to receive the light emitted by the phototransmitter. Strong signal to detect the concentration of oil fume. However, the optical receiver sometimes receives some invalid interfering light, which reduces the detection accuracy of the optical receiver. Contents of the invention [0003] An embodiment of the present invention provides a kitchen device. [0004] A kitchen device according t...
