Embodiment 1

[0036] like figure 1 The illustrated range hood capable of detecting the concentration of soot includes a housing 1, a fan 2 and a main control unit (not shown in the figure) that can control the rotational speed of the fan are arranged in the housing, and a fume collecting hood 3 is arranged under the housing 1; The main control unit is also connected with a photoelectric oil fume sensor that can detect the concentration of oil fume. The photoelectric oil fume sensor includes a detection light emitting device 4, a detection light receiving device 5 and a sensor circuit board (not shown in the figure) connected to the detection light receiving device. out), the detection light-emitting device 4 has a light-emitting portion 41 capable of emitting detection light, and the detection light-receiving device 5 has a light-receiving portion 51 that can receive the detection light emitted by the light-emitting portion; The power input and output end of the sensor circuit board is conn...

Embodiment 2

[0042] The difference from the first embodiment is that only the detection light emitting device 4 is provided with a protective structure for protecting the light emitting portion 41. The protective structure is the same as that described in the first embodiment. image 3 shown.

Embodiment 3

[0044] The difference from the first embodiment is that only the detection light receiving device 5 is provided with a protective structure for protecting the light receiving portion 51. The protective structure is the same as that described in the first embodiment. Figure 4 shown.

[0045] In addition, in addition to the structure described in the first embodiment, the protective structure can also have other forms: for example, there can be multiple blocking plates 66 in the tubular cavity, and they can be arranged at intervals, such as three, and two adjacent blocking plates The diameter of the through holes on the 66 can be the same or different, Figure 5 shown. The design of this multi-diameter labyrinth makes the inner diameter of the tubular cavity expand and shrink many times. When expanding, the oil fume obtains a radial diffusion driving force, and most of the oil fume entering the tube is diluted in this section and adheres to the inner wall of the tube. When sh...

Abstract

The invention relates to a range hood capable of detecting the concentration of oil fume, which comprises a casing, a smoke collecting hood is arranged under the casing, a fan and a main control unit capable of controlling the speed of the fan are arranged in the casing, and a main control unit is arranged on the casing. A photoelectric oil fume sensor connected to the unit that can detect the concentration of oil fume. The photoelectric oil fume sensor includes a detection light emitting device and a detection light receiving device. The detection light emitting device has a light emitting part that can emit detection light. The detection light receiving device has The light receiving part of the detection light emitted by the light emitting part; it is characterized in that: the detection light emitting device and the detection light receiving device are aligned with each other and arranged on two opposite sides of the smoke collecting hood or two opposite sides of the flue inside the housing; The detection light emitting device or / and the detection light receiving device further include a protective structure. The photoelectric oil fume sensor in the invention has good oil pollution resistance effect.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood capable of detecting the concentration of the range hood. Background technique [0002] The intelligent control of existing range hoods mostly relies on the accurate detection of relevant environmental indicators such as gas concentration, oil fume concentration, temperature, odor concentration, cooker switch, etc. by sensors. Among them, the automatic opening and closing of the range hood is mainly achieved by detecting the sudden change of these indicators from scratch, and the automatic control of the speed or gear of the range hood fan is mainly based on the size of the index value. [0003] For example, the Chinese Patent No. 20111003374.0 proposes a smoke detection system based on a camera, which can detect the amount of smoke, and then automatically control the operation of the range hood according to the smoke concentration. In this solution, a camera needs to be set up to co...
