[0047] As Figure 1 And Figure 2 As shown in the drawings, the utility model provides an oil fume treatment device, which can be a range hood, integrated stove and the like, and the embodiment of the present disclosure takes the range hood as an example for description, which comprises a shell 200, a fan (not shown in the drawings) and a movable part 300, wherein the fan is arranged in the interior of the shell 200, the movable part 300 comprises a smoke collecting cavity body 310 and a smoke collecting plate 320, the smoke collecting cavity body 310 can be extended or retracted relative to the shell 200, the smoke collecting cavity body 310 is provided with a smoke inlet 3101, and the smoke collecting plate 320 is arranged on the smoke collecting cavity body 310 and can be switched between a first state of opening the smoke inlet 3101 and a second state of plugging the smoke inlet 3101. Figure 2As shown, when the smoke collecting cavity body 310 extends out of the shell 200 and the smoke gathering plate 320 is in the first state, the oil fume is discharged after passing through the smoke inlet 3101, the inside of the smoke collecting cavity body 310 and the shell 200 in turn. When the smoke collecting cavity body 310 is retracted into the shell 200 and the smoke gathering plate 320 is in the second state, better retraction effect of the movable part 300 can be achieved. It should be noted that the above-mentioned range hood is only one type of telescopic range hood, and the range hood of the embodiment of the present disclosure can also be various types of range hoods such as top suction type, side suction type, ultra-thin type, etc. All types of range hoods are within the protection scope of the embodiment of the present disclosure.

[0048] In an optional embodiment, as shown in Figure 2 The operation panel assembly 100 further comprises a detection mechanism 40 electrically connected with a controller of the range hood, and the controller is further communicatively connected with the movable part 300 and the fan. A cooking bench 3000 is arranged below the range hood, and a cooking appliance 2000 is arranged on the cooking bench 3000. The detection mechanism 40 is arranged on the mounting assembly 600 and is used for detecting the temperature of a pot 4000 on the cooking appliance 2000. The controller can control the working state of the movable part 300 and the fan according to the temperature of the pot 4000 on the cooking appliance 2000, so as to realize adaptive adjustment of different working states of the range hood and the temperature of the pot 4000, and realize better absorption effect of the range hood on oil fume.

[0049] For example, the detection mechanism 40 can be set as an active infrared temperature sensor or a passive infrared temperature sensor. The active infrared temperature sensor emits infrared rays, which are reflected after contacting the measured object and are received by the active infrared temperature sensor again, so as to measure the temperature of the measured object. The passive infrared temperature sensor detects the infrared radiation energy of the object when the temperature of the object is higher than the thermodynamic zero, so as to detect the temperature of the measured object. In addition to the above two types, any infrared temperature sensor capable of realizing non-contact measurement of the temperature of the measured object is within the protection scope of the technical scheme of the present disclosure.

[0050] In an optional embodiment, as shown in Figure 2 Each cooking appliance 2000 is correspondingly provided with one detection mechanism 40, and each detection mechanism 40 can realize accurate detection of the temperature of the pot 4000 on the corresponding cooking appliance 2000. For example, the number of detection mechanisms 40 can be one, two, three or more, and the number of detection mechanisms 40 corresponds to the number of cooking appliances 2000.

[0051] In an optional embodiment, as shown in Figure 2As shown, the detection mechanism 40 is provided in two, and the stove 2000 of the optional embodiment is provided in two, each detection mechanism 40 corresponds to one stove 2000, which can realize the accurate detection of the temperature of the pot 4000 on the corresponding stove 2000 by the detection mechanism 40.

[0052] In an optional embodiment, as shown in Figure 2 As shown, the two detection mechanisms 40 are arranged on the two sides of the smoke collecting plate 320 along the left-right direction, and in addition, the detection signal M emitted by each detection mechanism 40 is located outside the smoke collecting plate 320, so as to avoid the interference of the smoke collecting plate 320 on the detection signal M, and ensure the accurate detection effect of each detection mechanism 40 on the temperature of the pot 4000.

[0053] As shown in Figure 1 and Figure 2 As shown, the range hood further comprises an operation panel assembly 100, the operation panel assembly 100 is arranged on the shell 200, and the operation panel assembly 100 is used for displaying icons 20, and a user can operate the icons 20 to realize different functions of the range hood. As shown in Figure 6 As shown, the existing operation panel assembly 100 comprises a transparent panel 10 and a light-emitting assembly, the transparent panel 10 is provided with at least two icons 20, and the light-emitting assembly comprises at least two light-emitting pieces 31, each light-emitting piece 31 can make the corresponding icon 20 emit light, but when the adjacent two light-emitting pieces 31 emit light, a light bar 800 will be displayed in the area between the adjacent two light-emitting pieces 31 on the transparent panel 10, which affects the suspension effect of the icon 20 on the transparent panel 10 when the icon 20 emits light, and also affects the display effect of the operation panel assembly 100.

[0054] After long-term exploration and research by researchers, it is found that the formation of the light bar 800 is mainly due to the mutual interference and superposition of light emitted by the adjacent two first light-emitting pieces 31, in order to solve the above problems, as shown in Figure 3 and Figure 4As shown, the range hood further comprises a projection device 900, and the operation panel assembly 100 further comprises a photonic crystal transparent film 30, which is attached to the side of the transparent panel 10, and the projection device 900 is used to project an image onto the photonic crystal transparent film 30 to form the icon 20. The photonic crystal transparent film 30 has photonic chip display technology, which only regulates the image projected by the projection device 900 and allows complete transmission of light in other directions, thereby forming a transparent and high-definition icon 20, ensuring that the icon 20 on the operation panel assembly 100 has a better floating feeling, and effectively improving the display effect of the operation panel assembly 100.

Exemplarily, the abutting portion 94 can be made of rubber, silica gel, plastic, metal and various materials.

[0080] In an optional embodiment, the baffle 642 is in sliding connection with the blocking member body 641, the blocking member 64 further comprises a power member (not shown in the figure), the power member comprises a power member body (not shown in the figure) and a power member output end (not shown in the figure) capable of sliding relative to the power member body, the power member output end is fixedly connected with the baffle 642, when the power member output end moves relative to the power member body, the power member output end can drive the baffle 642 to move, and the baffle 642 can be switched between the first state and the second state. Exemplarily, the power member can be a linear motor, a linear cylinder and the like, all structures capable of realizing linear output motion are within the protection scope of the embodiments of the present disclosure.
